Product Overview:

785nm, 100mW, 50 GHz Linewidth 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 and provides a narrow emission output. The PowerController low noise current source has been optimized to provide the highest levels of power 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 module. (For industrial integration we also offer the highly compact PowerController to be directly attached to the laser head or connected via a customized cable.)

Optional Accessories Available to Suit Your Application
