Product Overview:

785nm Raman Spectroscopy Laser | 100mW Wavelock™ Stabilized Laser Diode Module

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.

WAVELOCK™ VHG Stabilized for Demanding R&D Applications

- WAVELOCK™ VHG stabilized optimized for Raman Spectroscopy applications - Integrated precision temperature stabilization & low noise current source - Wavelength stability < 0.015nm - Power stability < 1% - Long coherence length

Turn-Key System with Controller Unit and Software

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 with the L-Tune GUI control software. (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.)
