Coherent (Santa Clara, CA) has expanded its OBIS family of plug-and-play smart laser modules with a new fiber-pigtailed (FP) option at several wavelengths, including 405nm, 488nm, and 640nm. The OBIS FP lasers are offered with 1 meter of single-mode, polarization-preserving fiber, terminating in a standard FC/APC connector. OBIS FP lasers achieve low noise and output stability due to two factors: an output beam with low beam drift to maintain efficient coupling, and telecom-type architecture and methods, such as laser welding to yield drift-free opto-mechanical coupling.
