MPBC’s new line of passively Mode-Locked Fiber Lasers are designed to address a range of market applications including semi-conductor inspection, micro-machining, metrology, multi-photon spectroscopy, and can be used as a seed source for optical amplifiers, and second harmonic generation. Based on an all-fiber design, the MLFL is highly reliable (10,000 hrs) and maintenance-free. To ensure an environmentally-stable linearly-polarized output and turnkey self-start operation, all components are made of polarization-maintaining fiber.
