4 STLB-SGR Series Q-Switched Nd:YAG Laser

STLB-SGR Series Super-Gaussian Resonator series Q-Switched Nd:YAG lasers combine VRM (variable reflectivity mirror) with unstable resonator design creating a cavity with large TEM00 mode volume for excitation and energy extraction. A “flat-top-hat” can be specified with uniform energy distribution or “VRM Gaussian” profiles.

STLB-GR Series close-coupled diffuse pump chamber delivers uniform pumping of the laser rod for optimum lasing excitation efficiency and allows for higher stored energy by eliminating parasitic oscillations within the pump chamber. The pump chamber uses chemically inert materials to withstand high pumping energy and absorb unwanted UV and IR radiation emitted by the flash lamps. One or more amplifiers can be added to the oscillator for higher energy output. With scientific or industrial grade models available, the STGR series will fit right in with your scientific research, medical or OEM industrial application.

Features:

  • Fundamental wavelength covers 2-6 J output

  • Higher harmonics available

  • Repetition rate up to 50 Hz

  • Injection seeded for narrow linewidth

  • RS232 and TTL interface for remote or external control

  • Invar structure inside

Applications:

  • Photo chemistry

  • Molecular chemistry

  • Non-linear optics

  • Laser illumination

  • LIDAR

  • Laser cleaning

  • Laser ablation

  • Optical remote sensing

  • LIF (Laser Induces Florescence)

  • PLD (Pulsed Laser Deposition)

  • Plasma diagnostics
