Temporal contrast is crucial for the interaction of ultraintense, ultrashort pulse lasers with matter. Seed laser sources that offer high temporal contrast are essential for enhancing overall temporal contrast. In this study, we demonstrate the generation of a high temporal contrast seed laser by spectral broadening and filtering of a Yb: CALGO femtosecond amplifier in an air-filled multi-pass cell (MPC).
