Pharos Series - High Power and High Energy Femtosecond Lasers

PHAROS is a diode pumped femtosecond laser with an integrated oscillator and amplifier. The amplifier delivers pulse energy > 2 mJ and output power > 20 W. The pulse duration is tunable from 190 fs to 10 ps. Included pulse picker allows pulse-on-demand operation and a variable repetition rate from single shot pulses to 1 MHz. The compact and robust optomechanical design as well as the temperature stabilized housing ensure stable operation.

PHAROS is a single-unit integrated femtosecond laser system combining millijoule pulse energies and high average powers. PHAROS features a mechanical and optical design optimized for industrial applications such as precise material processing. Compact size, integrated thermal stabilization system and sealed design allow PHAROS integration into machining workstations. The use of solid state laser diodes for pumping of Yb medium significantly reduces maintenance cost and provides long laser lifetime. Most of the PHAROS output parameters can be easily set via PC in seconds.

Tunability of laser output parameters allows PHAROS system to cover applications normally requiring different classes of lasers. Tunable parameters include: pulse duration (190 fs – 20 ps), repetition rate (single pulse to 1 MHz), pulse energy (up to 2 mJ) and average power (up to 20 W). Its deliverable power is sufficient for most of material processing applications at high machining speeds. The built‑in pulse picker allows convenient control of the laser output in pulse‑on‑demand mode. PHAROS compact and robust optomechanical design features stable laser operation across varying environments. PHAROS is equipped with an extensive software package which ensures smooth hands‑free operation.

Optical Parametric Amplifier I-OPA

  • Based on experience with ORPHEUS line
  • Manually tunable wavelength
  • Industrial grade design provides excellent long-term stability
  • Bandwidth limited or short‑pulse configurations available
  • CEP option available

I‑OPA is the first industrial grade optical parametric amplifier which features long-term stable output with a reliable hands-free operation. Manually tunable output wavelength extends application possibilities of a single laser source instead of requiring multiple lasers based on different technologies.

In comparison to standard ORPHEUS line devices, the I‑OPA lacks only a computer controlled wavelength selection. On the other hand, in-laser mounted design provides mechanical stability and eliminates the effects of air-turbulence ensuring stable long-term performance and minimizing energy fluctuations.

Automated Harmonics Generators

  • 515 nm, 343 nm, 257 nm and 206 nm
  • Output selection by software
  • Mounts directly on laser head and integrated into the system
  • Rugged, industrial grade mechanical design

PHAROS laser can be equipped with auto­mated harmonics modules. Selection of fundamental (1030 nm), second (515 nm), third (343 nm), fourth (257 nm) or fifth (206 nm) harmonic output is available through software control. Harmonics generators are designed to be used in industrial applications where a single output wavelength is desired. Modules are mounted directly on the output of the laser and integrated into the system.

In case more outputs are required simultaneously, then stand-alone HIRO harmonic generator is the solution.

Standalone Harmonics Generator Hiro

HIRO is a valuable option for PHAROS / CARBIDE lasers and FLINT oscilla­tors that provides high power harmonics radiation at 515 nm, 343 nm and 258 nm wavelengths. We offer several standard HIRO models (with open prospect of future upgrades) which meet most users’ needs. The active harmonic is selected by manual rotation of the knob – changing the harmonics will never take longer than a few seconds thanks to its unique layout and housing construction.

HIRO is the most customizable and upgradable harmonics generator available on the market. It can be easily modified to provide white light continuum, beam splitting / expanding / down‑collimating options integrated in the same housing as well as harmonics splitting that makes all three harmonics available at a time.

Please contact us for customized version of HIRO.
