Output pulse characteristics. (a) Peak power and pulse width for varying L. Pumping energy: 6.4 mJ/pulse, corresponding pumping duration: 200 μs. The solid lines indicate the calculated values, which agree well with the measured values. The thin dashed line indicates the minimum L achievable using the Nd:YAG and RIG film. (b) Output pulse shape with L = 10 mm. The peak power and pulse duration were 1.1 kW and 25 ns, respectively. Inset: output wavelength spectrum. Black circles show the measured data. Three peaks were observed at the wavelength of 1,064.54 (red line), 1,064.59 (blue line), and 1,064.66 nm (green line). The spectrum widths at each wavelength were 47, 39, and 35 pm, respectively.
