SANTA CLARA, Calif., May 23, 2011 — Coherent Inc. has released a 10-W continuous-wave green (532 nm) laser intended for pumping Ti:sapphire oscillators and amplifiers. The Verdi G10 is the highest power model in the Verdi G family, which uses proprietary next-generation optically pumped semiconductor laser (OPSL) technology to deliver high performance, good reliability and a compact size. The lasers do not suffer from either the “green noise” or thermal lensing issues that limit the performance of multimode lasers based on diode-pumped solid-state technology, according to the company. As a result, they exhibit noise of <0.02% rms across a wide frequency spectrum from 10 Hz to 100 MHz. The lack of thermal lensing means that the output power can be smoothly adjusted from 10% to 100% of the maximum value, with no effect on beam quality or the beam pointing stability of <2 μrad/°C. The laser is suitable for pumping ultrafast and continuous-wave Ti:sapphire laser systems for all applications in spectroscopy, pump-probe dynamics and materials research, including carrier-envelope-phase-stabilized systems, where achieving low phase noise is dependent upon using a low-noise pump laser. The device has sufficient power for pumping high-repetition-rate ultrafast amplifiers.
