A laser diode array side-pumped Nd:glass square rod amplifier of the dimensions 12 mm × 12 mm is designed.The fluorescence is evenly distributed in the Nd:glass amplifier.When the pump power is 66.32 kW,the small signal gain increases by 3.23 times.Under the condition of a 1 Hz repetition frequency,50 mJ of injected seedlight energy,and a 10 mm × 10 mm aperture,the output energy of the laser beam can reach 1.62 J during the four-pass amplification.The output energy stability of the laser pulse is 2.94%(RMS),and the square pulse distortion is smaller than 2.The energy amplification of the injected laser beam from millijoules to joules is realized.
A laser diode array side-pumped Nd: glass square rod amplifier of the dimensions 12 mm × 12 mm is designed. The fluorescence is evenly distributed in the Nd: glass amplifier. When the pump power is 66.32 kW, the small signal gain increases by 3.23 times. Unders the condition of a 1 Hz repetition frequency, 50 mJ of injected seedlight energy, and a 10 mm × 10 mm aperture, the output energy of the laser beam can reach 1.62 J during the four-pass amplification. The output energy stability of the laser pulse is 2.94% (RMS), and the square pulse distortion is smaller than 2. The energy amplification of the injected laser beam from millijoules to joules is realized.
