Request InfoCalmar LaserCalmar Laser Inc. has added a high-power 780-nm femtosecond fiber laser to its Mendocino family. Model FPL-05RFF0 offers >500 mW of output power and a pulse width of 150 fs in an ultracompact laser pointer-style package measuring 3 x 3 x 13.5 cm. It produces a 50-MHz train of femtosecond pulses that have a near-pedestal-free shape and good pulse-to-pulse stability. The output beam has roundness better than 90% and M2 <1.1, enabling optimal spatial resolution when used in conjunction with microscope systems. The laser is air-cooled and does not require a chiller.
