The FemtoLux green from EKSPLA is a Femtosecond Green Fiber Laser that 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. The 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 automatically tuned from 300 fs up to 5 ps. It provides more than 1.5 W average power at 515 nm and 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. This laser is ideal for marking and structuring, micromachining of brittle materials, photopolymerization and biological imaging applications.
