The 780 nm high power femtosecond fiber laser (FPL) is a passively mode-locked fiber laser that employs second harmonic generation to provide a stable short pulse output at 780 nm. The laser utilizes the proprietary Mendocino saturable absorber technology, which has been developed and perfected over a twenty-year period, to deliver reproducible mode-locking at turn-on with excellent stability and reliability. It provides a free-space output with power levels of over 150 mW and a short optical pulse of less than 90 fs. The high quality spatial mode ensures excellent focusability for tetrahertz generation and multiphoton microscopy applications. The laser also offers an RF 80 MHz synchronization output as a trigger signal.
The module (FPL-M) series features a robust architecture that is insensitive to shock and vibration. It can be used as a stand-alone laser system with a user-supplied 5 VDC power supply and is the perfect seed source for integration into demanding OEM applications. An advanced engineering design and consistent manufacturing process ensure the highest quality standards for volume production.
