In some important applications like multiphoton polymerization, writing of fiber Bragg gratings, volume modification of transparent materials, nonlinear microscopy, silicon and sapphire scribing, marking of some kind of materials, different wavelength than fundamental output is needed. Important point is that requirements for sufficient pulse energy as well as beam quality remains. Having in mind such needs, FemtoLux green , femtosecond fiber laser, was developed. Unlike other commercially used fiber lasers, FemtoLux provides perfectly linearly polarized light with polarization extinction ratio >1000 : 1. This allows generation of second harmonic with great efficiency better than 50% and excellent spatial beam and temporal pulse parameters.
Fiber based front-end allows multiple pulse train control functions like: wide range of operating pulse repetition rates, individual pulse gating up to 10 MHz, burst mode with active burst envelope shaping, real time pulse amplitude control. Pulse duration can also be tuned from 300 fs up to 5 ps. Providing more than 1.5 W average power, it’s reasonably high wall plug efficiency as well as smart heat management makes laser head passively cooled with only ~60 W of heat dissipations, when operating at full power.
