Manual or motorized tunable Littman/Metcalf laser system (LION) / Laser diodes
Our Littman/Metcalf laser systems use tunable external cavity diode lasers. They cover the wavelength range from 635 nm to 2450 nm and avoid modehop.
Manual or motorized tunable Littman/Metcalf laser system (LION) summary
Littman/Metcalf laser systems are excellent turn-key scientific lasers. The external cavity design allows excellent tuning, high output optical power up to 100mW and offers excellent quantum efficiency and high fiber coupling efficiency.
Littman/Metcalf lasers are perfect for applications such as spectroscopy, optical process control, interferometry, laser, seeding, non-linear optical processes or characterization of fiber optical systems.
Moreover, Littman/Metcalf laser systems can be tuned manually or thanks to a motor. In the motorized configuration, a precise and smooth tuning is done via DC motor (to avoid mode hopping). A fine tuning is also possible via piezo-actuator with a resolution better than 1 MHz.

How does our laser tune modehop-free ?
2 features defines the emission wavelength of a laser : the cavity mode and the amplification range of the gain medium.
Most diode lasers have wide gain region. So, it is necessary to put a wavelength selective medium inside of a cavity like a grating. In order to tune such as laser modehop-free, the grating defined wavelength need to be synchronized with the cavity defined wavelength. This synchronization is done by a simple rotation of the mirror. The adjustment of the pivot point is done during the wavelength scanning operation of our Littman/Metcalf laser system (patent n° 5,867,512).
