Calmar Laser Inc. has added a high-power 780-nm femtosecond fiber laser to its Mendocino family. The Mendocino 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. Pulse energy is up to 10 nJ, and pulse widths are down to 0.15 ps. The second-harmonic-generation passively mode-locked laser operates in the C-band and offers linearly polarized and radio-frequency synchronization output.
