| Abstract: | A dye laser containing an order amplifier which is pumped by a N2 laser is given in this paper. Moreover, the properties of BBOs doubling frequency for the dye laser are discussed and tunable SHG output from 217.5 um is obtained. The values of maximum conversion efficiency are 5 % (at 235.0nm), 9% (at 253 nm) and 12% (at 273.0 nm). The results of experiments correspond are in good consistency with theory. |
