Femtosecond Ti:Sapphire Laser System
_ OPCPA SEED

	The VENTEON \| PULSE : ONE OPCPA SEED represents the ideal front-end oscillator for broadband few-cycle OPCPA systems. Based on the VENTEON \| PULSE : ONE UB oscillator, the spectral bandwidth of this system allows for both, the generation of broadband few-cycle pulses as signal for the subsequent NOPA stage together with high power level @ 1030 nm for seeding an Yb-based amplifier serving as pump stage. Thereby both outputs are optical synchronized with respect to each other and their phase relation is preserved.
	The broadband signal pulses still feature a pulse duration as short as 5.5 fs and can be optionally stabilized with respect to their CEP without additionally spectral broadening and with the typical CEP performance of the VENTEON oscillators.
	The second output around 1030 nm provides exceptionally high energy > 30 pJ in a spectral bandwidth of 10 nm (FWHM) ideally suited as narrowband seed for the pump amplifiers. Optionally, the radiation coming directly from the VENTEON oscillator can be ordered with fiber pre-amplifier to deliver pulses with an energy > 1 nJ.
