Hentschel, M., Cheng, Z., Krausz, F., & Spielmann, C. (2000). Generation of 0.1-TW optical pulses with a single-stage Ti:sapphire amplifier at a 1-kHz repetition rate. APPLIED PHYSICS B-LASERS AND OPTICS, 70(S1), 61–64. https://doi.org/10.1007/s003400000327
We present a kHz-rate all-solid-state Ti: sapphire oscillator-amplifier system producing 1.8 mJ sub-20 fs pulses using a single multipass amplifier stage pumped by ≈ 10 mJ pulses. Compensation for gain narrowing and high-order dispersion is provided by chirped dielectric multilayer optics. The focused peak intensity approaches 10¹⁸ W/cm², making this compact high-repetition-rate source attractive for a wide range of high-field applications.
