Product Overview:

830nm, 500mW, Wavelock™ Laser Diode Module Overview

The WAVELOCK™ series laser diode modules are stabilized using a VHG, volume holographic grating. The WAVELOCK™ VHG provides exceptional wavelength stability and a narrowed spectral bandwidth for the most demanding Raman spectroscopy and analytical instrumentation applications. The volume holographic grating functions as an external cavity that locks the laser diode’s wavelength; this laser module provides a transversal multi-mode output.

The PowerController low noise current source has been optimized to provide the highest levels of power stability.

For this higher power laser diode module a water cooler is recommended to maintain maximum laser power and wavelength stability.

Optimized for Laser Output Stability

    • WAVELOCK™ VHG stabilized laser diode source offers industry leading wavelength and power stability
    • Optimized for Raman Spectroscopy applications
    • Integrated precision temperature stabilization & low noise current source help provide exceptional optical stability
    • Wavelength stability < 0.015nm
    • Power stability < 1%
    • High power and long coherence length

Versatile Power Supply Options

The Lambda Beam WAVELOCK™ VHG laser head requires a laser controller to provide power and control all operating parameters; this model includes the PowerController power supply. (For scientific applications and prototyping we recommend using our PowerController. For industrial integration we also offer the highly compact PowerBox to be directly attached to the laser head or connected via a customized cable.)

Optional Accessories Available to Suit Your Application
