Ondax’s LM Series Compact  Laser Modules incorporate the Ondax SureLock® VHG-stabilized laser diode to deliver steady, single frequency or spectrum narrowed performance in an ultra-compact footprint.

Offering both computer and integrated user controls, the LM Series includes precision temperature and current controls to deliver meter level coherence length (for single frequency versions), < 0.06nm linewidth (for spectrum narrowed versions) and 1% power stability with less than 1 minute warm-up. This tightly integrated package makes it the ideal choice for both OEM instrumentation and laboratory applications.
The LM Module is available in wavelengths from 404nm to 830nm.
