Optical SafetyLaser light, because of its special properties, can causesafety hazards not related to light from common sources.The safe use of lasers requires that all laser users and allpersons near the laser system understand the possibledanger. The safe use of the laser depends on the userunderstanding the instrument and the properties ofcoherent, strong beams of light.

DANGER!Direct eye contact with the outputbeam from the laser will causedamage and possible injury to theeyes.

- 3 -

Laser beams can burn volatile substances like alcohol,gasoline, ether and other solvents, and can damage light-sensitive elements in video cameras, photomultipliers,and photodiodes. Reflected beams can cause damage. Toprevent these conditions, follow these precautions:

• Follow all safety precautions in the operator’smanual.

• Be careful when using solvents in the area of the laser.

• Limit laser access to qualified users who know lasersafety practices and understand the possible danger.

• Never look directly into the laser light source or atscattered laser light from any reflective surface.

• Never sight down the beam into the source.

• Keep experimental setups at low heights to preventaccidental beam-eye encounter at eye level.

- 4 -

• As a precaution against accidental exposure to theoutput beam or its reflection, persons using thesystem must wear laser safety eyewear as required bythe wavelength being created.

• Use the laser in an enclosed room. Laser light remainscollimated for long distances and presents a possiblehazard if not controlled.

• Display warning signs in the area of the laser beam totell persons of the possible danger.

WARNING!Wearing laser safety eyewear can be ahazard and a benefit: They protect theeyes from possible exposure damage,but also block light at the laser wave-lengths, which prevents the operatorfrom seeing the beam. Always usecaution when wearing safety eyewear.

- 5 -

• Tell all persons using the laser of these precautions.

• Operate the laser in a room with controlled andrestricted access.

Electrical SafetyThe Coherent StingRay laser does not have dangerousvoltages. Do not disassemble the enclosure. There are nouser-serviceable components inside. All units can beoperated as assembled. Warranty is cancelled if theenclosure is disassembled.

Optional Software InstallationCoherent Connection software is included with thepurchase of a StingRay Controller or Controller Kit. Thesoftware can also be bought separately (1258561).

To install: 1) Close all programs. 2) Put the memorydrive into a USB port on your computer. 3) Double-clickthe .exe installation file. For complete operating instruc-tions refer to the Coherent StingRay Operator’s Manual(1223124), provided in PDF format on the StingRayUSB memory drive and on the Coherent website:www.Coherent.com/StingRay.

Laser InstallationOEM System

This section describes how to get the laser to run in CWmode without the laser controller. For more informa-tion—including specifics on modulation, interfacing,installation, and heatsinking—refer to the CoherentStingRay Operator's Manual (1223124), provided inPDF format on the StingRay USB memory drive and onthe Coherent website: www.Coherent.com/StingRay.

Refer to the “Optical Safety” topic in this guide and inthe Coherent StingRay Operator’s Manual (1223124) forthe optical safety information.

Note: In this configuration the laser is NOT CDRHcompliant for end-use applications. This laser will startemission when power is applied to the laser. Care shouldbe taken to use correct safety protocols when you operatethis laser in the OEM component configuration.

Laser InstallationCDRH-Compliant System

This section describes how to get the laser to run with thelaser controller. For more information—includingspecifics on modulation, interfacing, installation, andheatsinking—refer to the Coherent StingRay Operator'sManual (1223124), provided in PDF format on theStingRay USB memory drive and on the Coherentwebsite: www.Coherent.com/StingRay.

Refer to the “Optical Safety” topic in this guide and inthe Coherent StingRay Operator’s Manual (1223124) forthe optical safety information.

Note: In this configuration the laser is CDRH compliantfor end-use applications. The laser will not start emissionuntil the interlock and key switch are enabled and powerapplied to the controller. When these conditions are met,the laser will start emitting in 5 seconds (safety delay).

Required Material

• A mini-USB cable is needed to connect the lasercontroller to a PC. This cable is included with thepurchase of a StingRay Controller Kit (1231404) andis also sold separately (1108906).

• Coherent Connection Software—This software canbe used to interface with lasers that have the RS-232communication option enabled. The software isincluded with the purchase of a StingRay LaserController or can be purchased separately (1258561)for a StingRay laser (without a controller) that isconfigured with RS-232 communications. For infor-mation on communication protocols, refer to theCoherent StingRay Operator’s Manual (1223124).

MountingCorrectly mounting the laser diode for heat dissipation iscritical to laser lifetime and performance. Any lasermore than 20 mW should be mounted to supply correctheatsinking. Correct heatsinking needs to make fullradial contact with the clamping area. V-block mountsare not recommended. See the Coherent StingRay Oper-ator's Manual (1223124) for information on power dissi-pation and mounting specifications.
