Our single-mode (SM) fiber pump lasers emit low noise, precisely controlled levels of light at a specific wavelength out of a small-core fiber. SM pumps require the alignment of a 125 µm fiber with an 8 µm core to a similarly small laser emitter. This micro-alignment remains stable throughout wide temperature ranges and high shock/vibration environments.
The 400mW 974nm/976nm Butterfly Laser Diode is a 14-pin, TE-cooled, fiber-coupled, PM, single-mode pump laser module designed for high-performance applications.
