Femtolasers Produktions GmbH, Vienna, Austria, has released a new generation of Femtosource rainbow ultrafast oscillators, which offers carrier envelope phase (CEP) stabilized pulses with multiple simultaneous output options centered at 800 nm and 1030 nm with 100% mutual synchronization.
This Femtosource rainbow ultrafast Ti:Sapphire oscillator has multiple parallel output options centered at 800 nm and 1030 nm. It also has ultrafast sub-7 fs pulse duration with 200 mW average power; ultrabroad 260 nm spectral bandwidth with 200 mW for seeding applications; ultraclean 2.5 nJ for spectra up to 50 nm in bandwidth for high contrast seeding applications; ultrapower nearly 1 MW of peak power (500 mW, 7 fs pulses, non-CEP); and Ultra'red' 1030 nm, good for seeding OPCPA pump lasers.
The rugged CEP stabilization is based on Femtolasers' Difference Frequency Generation approach, which requires neither an interferometer nor nonlinear broadening of the spectrum. The new modular design makes an upgrade of a non-CEP stabilized to a CEP stabilized rainbow feasible.
