Vanguard

QUASI-CW MODE-LOCKED UV DPSS LASERS

  • 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

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.

Applications

1. Due to our continuous product improvement program, specifications are subject to change without notice.
2. Vanguard is a Class IV – High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to direct and reflected  
    beams. Diffuse as well as specular reflections can cause severe skin or eye damage.
