Highly Reliable Laser Diodes
IPG single emitter diodes are manufactured using telecom-proven technology and processes, and each wafer is qualified to rigorous telecommunication industry standards, which sets IPG apart from alternative industrial pump products using short-lived diode bars and bar-stack technologies. As a result, IPG single emitter diodes offer an order of magnitude higher pumping brightness and up to double the power efficiency of bar-stack pumps. Single emitter pumps are able to use simple water or even forced air cooling, as opposed to bars-stacks which require expensive, unreliable and complex microchannel coolers using high pressure deionized water.
IPG single emitter diode lifetimes exceed many thousand hours, orders of magnitude longer than the measured lifetimes of bar-stack alternatives. Unlike traditional alternatives, frequent on/off modulation of IPG diodes does not affect anticipated lifetime. IPG pumps are hermetically sealed to telecom standards, so are unaffected by the most aggressive industrial environments including humidity, dust and vibration. The exceptionally high reliability of IPG single emitter pumps is proven in laboratories and substantiated by excellent field reliability realized by customers worldwide..
