Product information "Vanguard™ Mode-Locked Quasi-CW Lasers"
355, 532 nm; Pulse Energy >31 nJ; Repetition Rate 80 MHz; Pulse Width <12 ps; Output Power 0.35->2 W
MKS Spectra-Physics’ Vanguard™ mode-locked 355 and 532 nm lasers are designed for OEM industrial applications. Pulse repetition rates are 80 MHz with <13 ps pulse width.
These quasi-CW lasers offer a superior solid-state alternative to replace CW gas lasers. They deliver ultra-low noise, near diffraction limited TEM00 output in a rugged industrial platform.
The Vanguard 355 nm laser is a frequency-tripled Nd:YVO4 laser, designed to bring solid-state reliability and low cost of ownership to applications such as wafer inspection, laser direct imaging, and picosecond machining. The Vanguard 532 nm laser is ideal for synchronous pumping of dye lasers.
