Quasar Hybrid Fiber Lasers
HIGH POWER UV & GREEN LASERS FOR FAST PRECISION MICROMACHINING
Spectra-Physics’ Quasar® is a breakthrough new hybrid fiber laser delivering industry-leading
high 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.

BREAKTHROUGH TECHNOLOGY

The Quasar Advantage

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 is an innovative
synergy of power, flexibility and control in a reliable 24/7 OEM laser for the most demanding
applications.

• >45 W UV (225 µJ) and >75 W green (375 µJ)

BREAKTHROUGH PERFORMANCE

• TimeShift Technology
- Constant pulse width over wide range of PRF
- Variable pulse width
- Pulse shaping
- Pulse splitting and Burst mode operation

Quasar 355-45 produces >45 W of UV and Quasar 532-75 produces >75 W of green output
power at >200 kHz pulse repetition frequency (PRF). Both models operate over a wide rep rate
range, from 0–1 MHz for ultra-high speed micromachining and output excellent beam
characteristics (M2 <1.3) with low noise. With TimeShift™ technology, pulse widths can be
varied at constant PRF or conversely, PRF can be varied at constant pulse width.

• High PRF from 0–1 MHz for fast processing
• Robust and reliable for OEM tools
• Datalog for critical performance monitoring and diagnostics

A P P L I C AT I O N S
• Glass cutting and drilling

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.
