FL-300 is a powerful femtosecond fiber laser with high frequency pulses. Amplifier compact size, no need to make adjustments when installed and air-cooling system allow to use FL-300 mode locked laser for industrial (EOM) and scientific purposes. Laser characteristics are optimal to perform ophthalmic surgery, spectroscopy and micromachining. FL-300 mode locked laser consists of two units (an oscillator and an amplifier), which are connected with optical and electrical interfaces, and it is shipped with all the technical documentation and controlling software. Oscillator unit may be used as a master oscillator for ultra narrow laser pulses with single-mode fiber output, if needed.
