These Nichia laser diodes, model number NDV4316, feature an optical output power of up to 120mW in CW mode. These devices offer single transverse mode of operation with a Gaussian far field beam profile. Their center peak wavelength is 405nm with a plus or minus 5nm wavelength tolerance. They are shipped in a standard 5.6mm (TO-18) can package and are mounted floating. They have a monitor photo-diode and zener diode internal to the package. These devices from Nichia are used in emerging applications in fluorescence spectroscopy as well as multiple emerging medical applications. They are the highest power native laser diodes with a single mode output at this wavelength.
