Littman & Littrow Lasers are Tunable external cavity diode lasers. Both types of laser has high passive stability; realizing the pivot axis of the tuning grating and the cavity adjustments via flex-mounts ensures the highest passive stability of our Littrow/Littman laser system. As a result, it achieves a robust and highly stable external cavity diode laser system with excellent values for the long-term laser linewidth.
