Wavelock - Free Space

Wavelock - Free Space

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.
