Overview

Vanguard™ lasers are state-of-the-art DPSS lasers specifically designed to produce exceptionally reliable quasi-CW output at 355 nm or 532 nm. This family of rugged OEM lasers use advanced mode-locking technology to deliver picosecond pulses with low noise and excellent TEM₀₀ mode quality.

High power, Quasi-CW UV output up to 2.5 W
High power, mode-locked 532 nm output up to 2 W
Outstanding power stability
Ultra-low noise
Near diffraction-limited TEM₀₀ output
