Tunable Littrow Lasers (LDL)

The MOGLabs LDL is a Littrow configuration extended cavity diode laser with monoblock chassis. There are no coil springs to vibrate. Machined from a solid block of aluminium alloy, this laser is compact, robust and stable. Precise, repeatable vertical alignment and grating rotation are decoupled to allow tuning the wavelength by tens of nanometres through the diode gain curve without realigning. The linewidth is below 100kHz for longer wavelengths and typically 200kHz in the blue. The LDL laser is designed particularly for wavelengths from 369nm to 500nm, and semi-hermetically sealed to reduce the effects of external air pressure variations.

The LDX/LDF variant allows for internal mounting of an isolator and even integration with our MLC Mini Laser Controller (pictured). Isolator options can be found here.
