  • >60 W UV (300 µJ) or >45 W UV (225 µJ)
  • >95 W green (475 µJ) or >75 W green (375 µJ)
  • TimeShift™ Technology
  • High PRF from 0 to 3.5 MHz for fast processing

The breakthrough performance of the Quasar ® series leads the industry with unprecedented highest UV average power and energy at high rep rate for fast micromachining. Quasar features novel TimeShift™ technology for programmable pulse profiles for the ultimate in process speed, flexibility, and control.

Breakthrough Technology

Quasar combines advanced fiber laser, power amplifier and patented harmonics technologies to achieve breakthrough results. This unique design exploits fiber laser flexibility and robustness to enable TimeShift technology. Adding Spectra-Physics’ exclusive power amplifier, Quasar enhances this flexibility at unprecedented high output power levels. Finally, with Spectra-Physics’ patented harmonics, known for exceptional stability, Quasar continues to provide an innovative synergy of power, flexibility and control in a reliable 24/7 OEM laser for the most demanding applications.

Breakthrough Performance

The Quasar 355-60 produces >60 W of UV output power at 200 kHz and 300 kHz, and >300 µJ pulse energy, complimenting Spectra-Physics’ breakthrough Quasar 355-45 laser. The Quasar 355-60 operates over a wide repetition rate range from 0–3.5 MHz, with pulse widths from <2 ns to >100 ns. The newest Quasar 532 nm rounds out the Quasar series with >95 W of green output power, with similar pulse width and PRF range as the Quasar 355-60, complementing Spectra-Physics’ breakthrough Quasar 532-75 laser.

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