摘　　要：A kilowatt diode-pumped solid state heat capacity laser is fabricated with a double-slab Nd：YAG. Using the theoretical model of heat capacity laser output laser characteristics, the relationships between the output power, temperature and time are obtained. The slab is 59 × 40×4.5mm^3 in size. The average pump power is 11.2kW, the repetition rate is i kHz, and the duty cycle is 20%. During the running time of i s, the output energy of the laser has a fluctuation with the maximal output energy at 2.06 J, and the maximal output average power is 2.06kW. At the end of the second, the output energy declines to about 50% compared to the beginning. The therma/effects can be improved with one slab cooled by water. The experimental results are consistent with the calculation data.A kilowatt diode-pumped solid state heat capacity laser is fabricated with a double-slab Nd：YAG.
