  PHAROS
 

“PHAROS” is a single-unit integrated femtosecond laser system combining millijoule pulse energies and high average power. It features market leading compact size for easy OEM integration and laboratory space saving. Most of “PHAROS” output  parameters can be easily set via control pad or PC tuning the laser for your particular application in seconds. Tunability of laser output parameters allow “PHAROS” system to cover applications normally requiring different class of lasers. Tunable parameters include: pulse duration (190 fs – 10 ps), repetition rate (single-pulse – 200 kHz, extendable to 1 MHz), pulse energy (up to 1.5 mJ) and average power (up to 15 W). Its deliverable power is abundant for a number of material processing applications, while achievable pulse durations and energies make it an attractive tool for the research applications.  
“PHAROS” compact and robust opto-mechanical design includes easy to replace modules (oscillator, amplifier and stretcher/compressor) with temperature stabilized and sealed housings ensuring stable laser operation within varying environments – features important for the OEM and industrial users. Standalone “PHAROS” oscillator (>2 W, <80 fs) is an excellent source of ultrashort pulses with an option to be locked to an external master clock. “PHAROS” is equipped with an extensive software package, which not only ensures its smooth hands-free operation, but also allows fast and easy integration into various processing devices.
 
FEATURES
  • Pulse duration <190 fs - 10 ps, 
  • Pulse energy up to 1.5 mJ, 
  • Average power up to 15 W, 
  • Flexibility in repetition rate: single-pulse to 200 kHz (extendable to 1 MHz),
  • Broad range of wavelength conversion options (harmonic generators, OPA, NOPA, continuum generators),
  • Rugged mechanical design with sealed modules replaceable on field.

APPLICATIONS
  • Micromachining,
  • Micro- and nano-structuring,
  • Nonlinear optics,
  • Time-resolved spectroscopy,
  • Biomedical applications.

  “PHAROS” is built upon traditional chirped pulse amplification technique, employing seed oscillator, regenerative amplifier and pulse stretcher/compressor modules. Kerr lens mode-locked oscillator, incorporating chirped mirrors for compensation of group velocity dispersion, typically delivers >700 mW output with sub-80 fs pulse duration. Regenerative amplifier is based on Yb:KGW lasing medium. Amplifier is non-collinearly pumped by one or two (respectively 4W or 6-15 W “PHAROS”) Light Conversion proprietary design high-brightness diode bar modules delivering up to 60 W of power. Conventional low loss BBO Pockels cells are used in regenerative amplifier and optional pulse picker at repetition rates up to 200 kHz (extendable to 1 MHz). The stretcher/compressor module is based on a single high efficiency  transmission grating with excellent power handling capability. Timing electronics, controls the operation of Pockels cells and monitors performance of the whole system. Separate modules of “PHAROS” system are interlinked by a set of industrial CAN bus microcontrollers. Operating parameters are adjustable via remote control module or external PC connected via USB interface.

Standard "PHAROS" system delivers pulse energies up to 0.2 mJ and pulse duration of 280 fs, somewhat varying with the repetition rate due to change in saturation level of the laser crystal. Short Pulse model PHAROS-SP incorporates modified resonator cavity with increased amplification bandwidth consequently delivering up to 1.5 mJ pulse energies and reduced pulses duration of 190 fs.
