M-FEMTO 3W <100 fs Ytterbium Modelocked Oscillator [PR114]

For academic research purposes, this integrated <100fs femtosecond laser oscillator is based on a diode-pumped Ytterbium solid-state laser, which is pumped by an external fiber-coupled laser diode. Pulse formation is done by soliton modelocking resulting in clean, sech^2-shaped pulses.

Average output power 1.5 … 3 W
Pulse energy, max. nJ ... uJ
Pulse duration (FWHM) <100 fs … <250 fs
Wavelength (center) 1030 … 1045 nm

This sub-100 (or <250) femtosecond laser oscillator is an integrated, hermetically sealed Ytterbium solid-state laser, which is pumped by an external fiber-coupled laser diode (19° rack housing).

Longer Pulse specifications can also be provided upon request.

With an Ytterbium-doped solid state laser crystal at its heart, this laser generates sub-100-fs pulses with excellent stability and robustness with respect to noise, modelocked-Q-switching instabilities and double pulsing. Modelocking is initiated by a Semiconductor Saturable Absorber Mirror (SeSAM) optimized for sub-100-fs operation, resulting in self-starting pulsed operation. The soliton-modelocking mechanism results in stable and spectrally clean pulses with a sech² pulse shape. The laser is pumped by the external, fiber-coupled laser diode.


Includes LDC-1000-980-LP laser diode and controller (19" rack housing), or equivalent.


Applications include seeding of amplifiers, pumping of OPOs, super-continuum generation, ultrafast spectroscopy, Terahertz generation, nano surgery & machining, etc.
