K2-1000-mini is a powerful ultralow noise turn-key laser for OEM integration. The laser is available as a modelocked femtosecond light source or as a dual-comb modelocked light source, producing two pulse trains from the same cavity (option). This laser is ideal for optical frequency comb applications, precision ranging, gas sensing, pump-probe as well as traditional laser oscillator applications, such as two-photon microscopy, amplifier seeding, and timing distribution.
