Spectra-Physics® (Santa Clara, CA) has introduced the Quasar, a breakthrough hybrid fiber laser that delivers high UV power at high repetition rates with TimeShift™ technology for precise micromachining. Combining advanced fiber laser, power amplifier and patented harmonics technologies, the new Quasar laser produces >40W UV power at high repetition rates. The novel TimeShift technology provides programmable pulse profiles to deliver the ultimate in process flexibility and control.
Quasar is also available with green output of >70 W. The integrated TimeShift technology optimizes the micromachining process with the capability to vary pulse width from 100 ns at constant repetition rates. Conversely, it provides the capability to maintain constant pulse width with varying repetition rates from <1 to 500 kHz. TimeShift technology also allows for pulse shaping and burst-mode operation for accelerating throughput while improving quality.
