LDL External Cavity Diode Laser
The MOGLabs LDL Littrow External Cavity Diode Laser is a research quality laser for advanced applications in atomic and quantum physics.
All springs – including flexures – have been removed to create a robust, stable, and vibrationally inert device. Grating rotation and vertical alignment are uncoupled, allowing simple tuning over the full diode wavelength range without realignment.
When used with a MOGLabs Diode Laser Controller, mode-hop-free scanning range of up to 40GHz and linewidth below 100 kHz can be achieved, with a broad range of AR coated and less expensive uncoated diode. Diode replacement and re-alignment are easily accomplished by the end-user. Wavelength options extend from 370nm to 1612nm, and powers up to 200mW extra-cavity.
