From graphic:Threshold power = 57 mW

Principle:The rate equation model for an opti-cally pumped four-level laser systemis determined. As lasing medium, aNd-YAG (Neodymium-Yttrium Alu-minium Garnet) rod has been select-ed which is pumped by means of asemiconductor diode laser.

The IR-power output of the Nd-YAGlaser is measured as a function of theoptical power input and the slope ef-ficiency as well as the thresholdpower are determined.

Finally, a KTP-crystal is inserted intothe laser cavity and frequency dou-bling is demonstrated. The quadraticrelationship between the power ofthe fundamental wave and the beampower for the second harmonic isthen evident.

Nd-YAG laser power output as a function of the pump power l = 808.4 nm.

Tasks:1. Set up the Nd-YAG laser and opti-

mize its power output.

2. The IR-power output of the Nd-YAG laser is to be measured as afunction of the pump power. Theslope efficiency and the thresholdpower are to be determined.

3. Verify the quadratic relationshipbetween the power of the funda-mental wave, with l = 1064 nm,and the beam power of the secondharmonic with l = 532 nm.

Thatis the pattern produced by a diffract-ing opening of arbitrary shape is thesame as a conjugate of the openingwould produce.

P1217600 Kerr effect

Principle:Monochromatic light, which is po-larised vertical impinges on a PLZTelement (lead-lanthanum-zirconi-um-titanium preparation) rotated inits support by 45° against the verti-cal.

An electric field is applied to thePLZT element (Kerr cell) and causesthe latter to become double refract-ing. The phase difference betweenthe ordinary and the extraordinarybeams after the PLZT element isrecorded as a function of the appliedvoltage. It is shown that the differ-ence of phase is proportional to thesquare of the electric field intensity,due to the applied voltage.

Tasks:1. The phase difference between the

ordinary and the extraordinarylight beam is recorded for diffe-rent voltages applied to the PLZTelement, that is, for different fieldintensities. The half wavelengthvoltages U(l/2) must be deter-mined.

2. By plotting the square of the ap-plied voltage against the phasedifference between the ordinaryand the extraordinary beam, it isshown that the relation betweenboth magnitudes is approximatelylinear. The Kerr constant is calcu-lated from the slope of thestraight line.

Relative light intensity I/I0 after analyser A as a function of the voltage Uapplied to the Kerr cell and of phase shift between the ordinary and theextraordinary beams.

P1290400 Transmission hologram with expansion system

Principle:In contrast to normal photography ahologram can store informationabout the three-dimensionality of anobject. To capture the three-dimen-sionality of an object, the film storesnot only the amplitude but also thephase of the light rays. To achievethis, a coherent light beam (laserlight) is split into an object and a ref-erence beam by being passedthrough a beam splitter. These beamsinterfere in the plane of the holo-graphic film. The hologram is recon-

structed with the reference beamwhich was also used to record thehologram.

Experimental set-up for the image-capture of a transmission hologram usingthe optical expansion system.

Tasks:1. Capture the holographic image of

an object.

2. Perform the development andbleaching of this phase hologram.

Principle:– In real time procedures, alter-

ations of an object are directly ob-served. A hologram is recordedunder the initial object conditionsand remains in exactly the sameposition (at exactly the sameplace) where it was located duringthe image-capture procedurewhile it is being developed.

– The hologram is reconstructedwith the reference beam and theobject is illuminated with the ob-ject beam (both waves are un-changed with respect to the cap-tured image). The light scatteredby the object interferes with thereconstructed light wave of thehologram.

– During the occurrence of minoralterations (e.g. bending) of theobject, interference fringes be-come visible on observing thehologram.

Student System “Advanced Optics” and Laser Physics

Experimental System “Advanced Optics”

This experimental system allows many important experiments in

Geometrical optics Holography Wave optics Interferometry Applied optics Fourier optics

to be performed.

All experiments are supported by corresponding handbooks, which containdetailed descriptions of experimental set-ups and procedures, as well asresults of measurements.

By use of a base plate and magnetically held adjustment devices, which canbe positioned jerkfree, 1 and 2 dimensional measuring set-ups with laser lightsources can be quickly and dependably realized. By deflecting the light path,experiments with larger focal lengths can also be carried out on the baseplate.

The high inherent stiffness and vibration damping of the base plate enablessensitive interferometer arrangements to be set up.Experimental set up for transmission hologram (LH4 – P1290300)

Optical base plate 08700.00For setting up magnetically adheringoptical components. Rigid and vibra-tion-damped working base made ofsteel plate. With corrosion protection,NEXTEL® plastic coating and im-printed grid (5×5) cm. Three fixedadapter sleeves for laser and lasershutter. With rubber feet for non-slipworking. Base plate size (mm) 590×430×24Mass 7 kg

Optical base plate in experimental case 08700.01Design as for base plate 08700.00,however with vibration-dampedstorage in the base of a case. Bottomclamp screws. When carrying out theexperiments, the base plate remainsin the bottom of the case. Separatecase hood with lock.Case dimensions (mm) 620×460×280Mass 13 kg

The practical system enables all im-portant experiments in • Geometric optics• Wave optics (diffraction, interfer-

ence, polarisation and refraction,Kerr and Faraday effect)

• Holography ( white light, transmis-sion and transfer holograms, aver-age time and real time holography)

• Interferometry (Michelson, Mach-Zehnder, Fabry-Perot, Sagnac,Twyman-Green interferometer, aswell as the insert for producingnon-optical phenomena such ase.g. measurement of magnetostric-tions).

• Fourier optics, diffusion of light,optical Doppler effect and laserDoppler anemometry to be carriedout.

Three didactic Laser systems are available to investigate the fundamental working principles and characteristics of lasers:

• Didactic system “Noble Gas Laser” (Helium-Neon-Laser)

• Didactic system “Solid State Laser” (Nd-YAG-Laser)

• Didactic system “Molecular Gas Laser” (CO2-Laser)” See pages 6 to 8

With the aid of a base plate and mag-netic adhering holders, which can bepositioned jolt-free, 1 and 2 dimen-sional measuring arrangements canbe quickly and reliably realised usinglaser light sources. By folding thelight paths experiments with largerfocal distances can also be carriedout on the working base. The high stiffness and vibrationdamping of the base plate allowssensitive interferometer arrange-ments to be set up. The base platewith hooded case 08700.01 is rec-ommended for the use of particular-ly vibration-sensitive applications,which is accommodated with partic-ular vibration-damping in the bot-tom of a transport case.

Si-Photodetector with amplifier 08735.00

This silicon photodiode with a built in transconductance amplifier is designed for precision, linearphotometric measurements over 6 decades at high interference levels. It works in connection withthe control unit 08735.99The diode is supplied with a front lens which can be partly covered by a screw-on slit diaphragmfor measurements with a higher local resolution. A second diaphragm, that slides onto the firstone, can be used to alter the entrance aperture in a variable fashion. Thereby it is possible to measure high light intensities without reaching the saturation level of the amplifier.

In connection with the Si-Photodetector 08735.00 it serves for photometric measurements of lowdirect- or alternating light signals. It is especially useful for photometric measurements in LDA andfibre optics experiments.It supplies the working voltage for the Si- Photodetector 08735.00. As outputs it offers a monitorsignal, a variable gain output for alternating light signals and an output that is filtered via a band-pass filter (200 Hz…10kHz).
