Coherent Inc.Request Info
Coherent Inc. has unveiled the Verdi G8, a high-power, 532-nm scientific-grade continuous-wave green laser based on proprietary optically pumped semiconductor laser (OPSL) technology, where the rod-based gain medium is replaced with a semiconductor chip. With 8 W of output in a TEM00 beam, the instrument provides a next-generation solution for pumping Ti:sapphire-based ultrafast laser oscillators in applications such as time-resolved and Raman spectroscopy, pump-probe dynamics and materials research. As with other Verdi G lasers, it produces low noise of <0.03% rms, and its short upper laser lifetime eliminates so-called “green noise.” The thin OPSL chip (a few microns) prevents thermal lensing effects that are present in all diode-pumped solid-state lasers. Other applications include scientific research, terahertz generation, optical tweezers, amplifier seeding, ceramic processing, laser inspection and optical data storage.
