We demonstrate, for the first time to our knowledge, multikilohertz operation of a double-stage optical parametric chirped pulse amplifier with periodically poled stoichiometric Li Ta O 3 crystals, seeded by a homemade Cr:forsterite oscillator operating at 1235 nm . The repetition rate of the amplifier could easily be tuned without the use of electro-optic modulators by using a repetition-rate-tunable kilohertz pump laser operating at 532 nm and a time-synchronization unit. Amplified total ( signal + idler ) energies of 55.9 and 36.2 μ J were achieved at 1 and 5 kHz , respectively. After recompression, the pulse width of amplified idler pulses at 1235 nm amounted to 530 fs .
