Coherent Verdi G-Series CW Laser

Family of high power OPSL and DPSS lasers with CW power up to 20W at 532nm

Coherent

Based on optically pumped semiconductor laser (OPSL) technology, the new Verdi G-Series is suited for Ti:S pumping and enables the lowest CW noise applications from 2W, 5W, 7W, 8W, 10W, 12W, 15W, 18W and 20W of 532nm.

The Verdi G-Series is based on OPSL technology where the rod-based gain medium is replaced with a robust and versatile semiconductor chip. OPSL output power can be changed without affecting beam parameters due to the ultra-thin gain medium (ie, no thermal lensing issues). In addition, the short upper-state lifetime of the OPS chip removes the "green noise" problem as seen with the sum frequency generation (SFG) noise in multi-longitudinal mode DPSS lasers. Single longitudinal mode options are available for up to 5W.

OPSL technology enables:

  • No thermal lensing - OPS chip allows power to be changed without affecting beam parameters
  • No "green noise" - lowest RMS noise spec <0.02% (from 10Hz to 100MHz) with OPS chip's short upper state lifetime
  • Simplified optical cavity and system design with fewer components makes it 50% in footprint compared to systems from other suppliers
  • Wavelength flexibility and power scalability - offers future path to new wavelengths and higher power
  • State-of-the-art AAA pump diode material
  • Features PermAlign™ technology
  • Lower cost of ownership
