Abstract
We demonstrate a single-stage multipass cell (MPC) compressor driven directly by a 500 nJ, 5 W, 120 fs, 10 MHz oscillator that delivers efficient spectral broadening from 800 to 1200 nm with >75% transmission. The compressed pulses approach the Fourier limit (FTL) of 8.1 fs, representing, to the best of our knowledge, the first realization of supercontinuum (SC) generation and compression in a single-stage MPC at such low, MW-level, input peak power. This compact, high-repetition-rate source holds strong potential for multiphoton microscopy and coherent Raman imaging.
