SINGLE-MODE PUMP LASERS
SM pumps (often referred to as Fabry-Perot lasers) require the alignment of a 125 μm fiber with an 8 μm core to a similarly small laser emitter. This micro-alignment must stay true and stable throughout wide temperature ranges and high shock/vibration environments. G&H meets the challenge with a series of cooled and uncooled diode laser products ruggedized and tested to Telcordia standards to meet the needs of demanding industrial, military, and space environments.
SM pumps are most commonly used for EDFA (erbium doped fiber amplifier) and fiber laser pumping applications. By selecting and stabilizing the wavelength closely to the doped absorption peak, the pump enables the maximum efficiency and light output from the system.
MULTI-MODE PUMP LASERS
Typically used for Erbium and Ytterbium fiber amplifiers (EDFA and YDFAs), multi-mode lasers offer a large amount of power out of a large core fiber for pumping of the doped fiber gain medium in order to amplify the signal. Other applications of MM pump lasers benefit from fiber-coupled, wavelength-specific light being delivered directly to the work piece.
G&H offers a variety of options to meet customer needs. Cooled options allow for wavelength tuning of the output for even greater wavelength control of the laser while uncooled options allow for higher power output since the heat is conducted directly to the mounting surface.
