Verdi G Series

Based on optically pumped semiconductor laser (OPSL) technology, the Verdi G-Series is suited for Ti:Sapphire pumping and enables the lowest CW noise applications from 2W, 5W, 7W, 8W, 10W, 12W, 15W, 18W, and 20W at532 nm.

High-Power Optically Pumped Semiconductor Lasers (OPSL)

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 (i.e. no thermal lensing issues). In addition, the short upper-state lifetime of the OPS chip removes the “green noise” problem as seen with sum frequency generated (SFG) noise in multi-longitudinal mode DPSS lasers. Single longitudinal mode options are available up to 5W. See the Verdi G-Series whitepapers for more details.
