A kHz 213 nm DUV solid-state-laser was developed adopting LD side-pumping configuration and electro-optical
Q
-switched techniques. A fundamental frequency radiation with the output power of 10 W was presented. The laser system could operate stably at the wavelength of 213 nm using multiple frequency techniques. When the pumping current of LD is 80 A
the maximum average output power of 213 nm beam arrives at 151 mW with the repetition rate of 1 kHz
the pulse width of 10 ns
and the power instability of 3%. Then
the polarization matching of the laser beam in the nonlinear crystal was analyzed. Furthermore
the operation properties of the laser system were studied detailedly under different repetition rates.
