Quasar® Hybrid Fiber LasersSpectra-Physics’ Quasar® is a breakthrough new hybrid fiber laser delivering industry-leadinghigh power UV and green at high repetition rates. Quasar features novel TimeShift™technology for programmable pulse profiles for the ultimate in process speed, flexibility,and control.

B R E A K T H R O U G H T E C H N O L O G YQuasar combines advanced fiber laser, power amplifier and patented harmonics technologiesto achieve breakthrough results. This unique design exploits fiber laser flexibility androbustness to enable TimeShift technology. Adding Spectra-Physics’ exclusive power amplifier,Quasar enhances this flexibility at unprecedented high output power levels. Finally, withSpectra-Physics’ patented harmonics, known for exceptional stability, Quasar is an innovativesynergy of power, flexibility and control in a reliable 24/7 OEM laser for the most demandingapplications.

B R E A K T H R O U G H P E R F O R M A N C EQuasar 355-40 produces >40 W of UV and Quasar 532-70 produces >70 W of green outputpower at >200 kHz pulse repetition frequency (PRF). Both models operate over a wide rep raterange, from 1–500 kHz for ultra-high speed micromachining and output excellent beamcharacteristics (M2 <1.3) with low noise. With TimeShift™ technology, pulse widths can bevaried at constant PRF or conversely, PRF can be varied at constant pulse width.

Quasar is designed, built, and tested to stringent quality standards for reliable continuousoperation in demanding 24/7 manufacturing environments. The built-in ALPS (Active LaserPurification System) helps sustain that performance for long life. And finally, Quasar lasers’automatic data logging software monitors all key laser performance parameters over the lifeof the laser, providing a powerful service feature and product reliability tool.

TimeShift™ Technology – Expanding and/or Compressing (Controlling) Output in the Time Domain to Enhance Utilization

Quasar is the first laser of this class to offer TimeShift technology, which enables pulse energy programmability in the time domain. By controlling the laserpulse (width and shape) in time and repetition rate, material removal and/or modification in micromachining becomes more efficient, thereby increasingprocess speed and quality. Utilizing TimeShift in conjunction with high UV or green power at a higher repetition rate means Quasar can process morematerials faster, and with greater quality. TimeShift enables pulse width variation, as well as pulse splitting and burst mode operation. Pulse widths from<10 ns to >100 ns can be created at a constant PRF or conversely, maintain constant pulse width with varying repetition rate from 1 to 500 kHz.

TimeShift Constant Pulse Width vs PRF

Unlike conventional Q-switched lasers, Quasar’s TimeShift technology canmaintain constant pulse width over a wide range of PRF. Constant pulsewidth means the peak power remains more constant allowing for moreconsistent process results at higher speeds.

Actual Pulse Traces of Constant Pulse Widths vs PRF

TimeShift Variable Pulse Width and Pulse Shaping

Varying the pulse width for a given PRF can be used to optimize thematerial interaction. By changing the energy and intensity within a pulse(pulse shaping), the heating or cooling of the material is further optimized.

TimeShift Pulse Splitting and Burst Mode

By splitting the pulses at a given PRF, the material is allowed to dissipatethe heat or plasma such that more efficient material removal is possible.By altering the number, spacing, and relativity intensity of pulses withinthe burst, the spatial-temporal thermal profile in the work piece can beprecisely tailored, increasing process speed and/or quality.

Pulse Width vs Repetition Rate1

1. Typically measured performance; not a guaranteed or warranted specification.2. Vertical range on oscilloscope set so that pulse peak is 75% of window.

1. Due to our continuous product improvement program, specifications may change without notice.2. All test specs are at 10 ns at 300 kHz with diode current set to achieve 40 W 355 nm. For 70 W 532 nm, all test specs are at 10 ns at 200 kHz.3. Applies at 10 ns over the repetition rate range of 250 kHz to 400 kHz, using the appropriate TimeShift setup at the same input current set to achieve40 W 355 nm at 300 kHz. Applies at 10 ns at 200 kHz for 70 W 532 nm version.4. The nominal pulse width is 10 ns. Alternative/programmable pulse widths using TimeShift will change power and beam parameter performance.Contact Spectra-Physics for more information.5.
