The internal semiconductor lasers are based upon InGaAsP buried heterostructure (BH) technology and fabricated by the Metal Organic Vapor Phase Epitaxy (MOVPE) process, resulting in long lifetimes and modest threshold currents. LSCX110 packages include a photodiode for monitoring the laser output, a thermistor for monitoring laser heatsink temperature and a Peltier effect thermoelectric cooler (TEC). A heatsink mounting flange is incorporated into the base of the 14 pin “butterfly” package and a “bullhorn” type flange is used on the 14 pin DIL package. Laser Safety Warning This device is a Class IIIb (3b) Laser Product. It may emit invisible laser radiation if operated with the fiber pigtail disconnected. To avoid possible eye damage do not look into an unconnected fiber pigtail during laser operation. Do not exceed specified operating limits. 460 5963-5308E (1/95) 1 page Performance Specifications (cont'd.)
