Diode Laser Frequency Control and cw Raman Lasers

This group is focusing on frequency control and locking of external cavity diode lasers. Applications include new products for wavelength division multiplexing in telecommunication systems and mini-lidar transmitters and receivers for water vapor detection. A new area of interest is in cw Raman conversion of diode lasers to wavelengths not available with current diode lasers. To do this, high finesse cavities coated for multiple wavelengths are used to reduce the thresholds for this new laser to the milliwatt level.
