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.

355 nm Applications

Wafer inspection
Laser direct imaging
Picosecond machining
Polyimide cutting and drilling
LED processing
Laser doped selective emitters (LDSE)
Various micro-material processing
Cell sorting

532 nm Applications

Synchronous pumping of dye lasers
Laser doped selective emitters (LDSE)
Photovoltaic scribing
Micro-material processing
