High-repetition-rate two-color pump-probe system directly pumped by a femtosecond ytterbium oscillator.
By exploiting optical parametric generation in periodically poled lithium niobate crystals driven by a cavity-dumped Yb:KYW mode-locked laser, we realized a two-color pump-probe system tunable in the near- and mid-IR with 1 MHz repetition rate, 300 fs temporal resolution, and sensitivity down to 10(-5).
