Calmar 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. Designed for OEM and scientific biophotonics applications, the turnkey device is nearly 300 times smaller than comparable-power femtosecond Ti:sapphire laser systems, according to the company.
