Krypton Discharge Lamps

Krypton discharge lamps exist primarily only in the high wattage long arc format. It is a lamp that evolved out of the laser science business, and they have only one application - the optical pumping of Neodymium : YAG lasers. Their strong shortwave infra-red radiation between 750 and 900nm is perfectly suited to this application in which the Nd:YAG crystals are strongly absorbing.

As a light source the krypton discharge is rather inefficient, achieving only some 30 lumens per watt. Like xenon, its emission spectrum is fairly well balanced over the visible 380-780nm range, thus the light has a whiteish appearance and the colour rendering properties are good by comparison with other pure gas discharge lamps.
