The new Spectra-Physics® Quasar® UV80 laser offers industry-leading high power of >80 W UV, >400 µJ pulse energy, and excellent single-mode beam quality. The new laser’s TimeShift™ programmable pulse capability results in adjustable pulse widths, pulse shapes and repetition rates for laser micromachining process optimization. The Quasar UV80 laser is ideal for applications in high throughput manufacturing of electronic packages and components, ceramics, PC boards, semiconductors, solar panels, lithium-ion batteries, and lightweight carbon fiber reinforced polymer (CFRP) parts.

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

Performance
The Quasar UV80 produces >80 W of UV output power at specification point 200 kHz 10 ns and >400 µJ pulse energy, complementing Spectra-Physics’ Quasar UV45, UV60 and UV60-Turbo lasers. The Quasar UV80 operates over a wide repetition rate range from 0–3.5 MHz, with pulse widths from <2 ns to >100 ns. The Quasar UV60 produces >60 W of UV output power at specification point 300 kHz 10 ns. The Quasar UV60-Turbo, optimized for high repetition rate performance, produces >38 W of UV output power at specification point 3 MHz 2 ns. The Quasar UV60-Turbo is an excellent match for high speed polygon scanning systems. The Quasar GR95 produces >95 W of green output power, with similar pulse width and PRF range as the Quasar UV60, complementing Spectra-Physics’ Quasar UV45 laser.

Reliable Continuous Operation
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. A customer version of this software is also available.

TimeShift Technology
Quasar offers TimeShift technology which enables pulse energy programmability in the time domain. By controlling the laser pulse (width and shape) in time and repetition rate, material removal and/or modification in micromachining becomes more efficient, thereby increasing process speed and quality. Utilizing TimeShift in conjunction with high UV or green power at a higher repetition rate means Quasar can process more materials faster, and with greater quality. TimeShift enables pulse width variation, as well as pulse splitting and burst mode operation. For the Quasar UV80, UV60, UV60-Turbo and GR95 models, pulse widths from <2 ns to >100 ns can be created at a constant repetition rate or conversely, maintain constant pulse width with varying repetition rate from 0 to 3.5 MHz. A set of standard TimeShift waveforms is provided with each Quasar. The TimeShift GUI, which enables users to develop custom waveforms, is available at an additional cost.
