플래시 램프로 펌핑한 Nd:YAG 레이저의 1.444 ㎛ 출력 특성

We investigated the output characteristics of Nd:YAG lasers at wavelength of 1444 ㎚, which were pumped by 450 Xe-flashlamp, 700 torr Kr-flashlamp and 700 torr Kr-flashlamp. With a Xe-flashlamp of 700 torr of gas pressure, the pulse energy of 0.738 J was obtained with repetition rate of 9.16 ㎐ and pumping pulse width of 400 ㎳. In case pumping pulse width of 5 ㎳ and repetition rate of 1 ㎐, 700 torr Kr-flashlamp showed the highest pulse energy of 1.44 J.
