Coherent Verdi G-Series CW Laser

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
