White-Light Seeded, Collinear OPCPA Front-End for LPA Drive Lasers at 800 nm

Laser plasma accelerators (LPAs) are typically driven by high-intensity Titanium: Sapphire (Ti:Sa) lasers that need to produce pulses with high quality in order to generate excellent electron bunches [1]. Key aspects for the generation of electron bunches with low energy spread are the pulse energy jitter, wavefront stability and central wavelength stability [2]. The requirement for high stability in combination with high beam quality therefore places stringent demands on the entire system, starting with the seed laser.
