First dual-comb modelocked diode-pumped solid-state laser: Dual-comb diode-pumped Yb:CaF2 laser simultaneously generates two modelocked pulse trains at 1050 nm with 175-fs, 3.2-nJ pulses and an average power of 440 mW in each beam. The average repetition rate is 137 MHz, and we set the repetition rate difference to 1 kHz using birefringent multiplexing. Equivalent time sampling resp. ASOPS is demonstrated with the free running laser.
