摘要：
We report on a high energy,high repetition rate Ho:YAG master oscillator and power amplifier(MOPA),resonantly dual-end-pumped by Tm:YLF lasers at room temperature.At the pulse repetition frequency of 1 kHz,we demonstrate a maximum energy of 30 mJ per pulse with a 28.2ns pulse width in a Ho:YAG oscillator system resonantly double-end-pumped by Tm:YLF lasers.A maximum energy of 52 mJ per pulse with a 30.5ns pulse width is achieved in the Ho:YAG amplifier,corresponding to a peak power of approximately 1.7 MW.The output wavelength is at 2090.6nm and 2096.9nm,and a beam quality factor of M2～2.1 is achieved.
