我们证明，第一次，我们的知识，multikilohertz操作的双级光学参量啁啾脉冲放大器与周期性极化的化学计量比的钽酸锂晶体，由自制的Cr：镁橄榄石振荡器工作在1235 nm的种子。放大器的重复频率可以很容易地调谐，而无需使用电光调制器，通过使用重复频率可调谐的千赫泵浦激光器工作在532 nm和一个时间同步单元。放大的总能量（信号+空闲）分别为55.9和36.2微焦耳，在1和5 kHz。在再压缩之后，在1235 nm处放大的闲频脉冲的脉冲宽度达到530 fs。
We demonstrate, for the first time to our knowledge, multikilohertz operation of a double-stage optical parametric chirped pulse amplifier with periodically poled stoichiometric LiTaO3 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 microJ were achieved at 1 and 5 kHz, respectively. After recompression, the pulse width of amplified idler pulses at 1235 nm amounted to 530 fs.
