Features

Overview

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 UV80 produces >80 W of UV output power at specification point 200 kHz 10 ns and >400 µJ pulse energy, complementing Spectra-Physics’ breakthrough 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’ breakthrough 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 is the first laser of this class to offer 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.

  • TimeShift Constant Pulse Width vs Pulse Repetition Frequencies (PRF): Unlike conventional Q-switched lasers, Quasar’s TimeShift technology can maintain constant pulse width over a wide range of repetition rates or pulse repetition frequencies (PRF). Constant pulse width means the peak power remains more constant, allowing for more consistent process results at higher speeds.
  • TimeShift Variable Pulse Width and Pulse Shaping: Varying the pulse width for a given PRF can be used to optimize the material 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 dissipate the heat or plasma such that more efficient material removal is possible. By altering the number, spacing, and relativity intensity of pulses within the burst, the spatial-temporal thermal profile in the work piece can be precisely tailored, increasing process speed and/or quality.

Compatible Power Sensors

To verify and analyze the output power of your Quasar laser, we recommend the Ophir F150A-BB-26 (7Z02727) or  L50(150)A-PF-35 (7Z02737) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the ophiropt.com website.  Other Ophir sensors and meters may also be suitable for the Quasar, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
