Coherent’s new LMFC Series High Power Multimode Fiber Coupled Laser Modules set a new standard for power and performance. Incorporating a SureLock™ VHG-stabilized laser diode, the LMFC delivers steady wavelength stabilized performance in an ultra-compact, fiber coupled module. The LMFC is available in both single-mode, single-frequency configurations (with either PM or SM fiber) as well as multi-mode, spectrum narrowed versions for higher power. With both computer and integrated user controls, the LMFC Series includes precision temperature and current controls to deliver better than 1% power stability with less than 1 minute warm-up. This tightly integrated package makes it the ideal choice for both OEM instrumentation and laboratory applications.
Single mode versions are available from 405 nm to 830 nm, multimode high-power versions in 785 nm, 830 nm, 976 nm, and 1064 nm.
