Lambda beam Wavelock lasers are wavelength-stabilised, single-longitudinal-mode lasers. A stabilising element locks the emission to a narrow line that stays put over time and temperature.

Key specifications
- Single longitudinal mode with high wavelength stability
- Long coherence length for interferometry and holography
- Output up to about 500 mW depending on wavelength (405–976 nm)
- Power stability better than 1 % over 10 hours; noise below 2 % RMS
- Analog or digital modulation: up to 1.5 MHz with the PowerBox, up to 0.5 MHz with the PowerController
How to choose
Wavelock lasers suit Raman spectroscopy, interferometry, holography and metrology, where a drifting wavelength would blur the measurement. 785 nm and 532 nm are the usual choices for Raman.
