双波长Nd：YAG脉冲激光器的实验研究

Experimental Research on Dual Wavelength Nd: YAG Pulsed Laser

根据多波长同时振荡条件，我们建立了大能量１０６４ｎｍ和１３１８ｎｍ同时运转的双波长脉冲Ｎｄ：ＹＡＧ激光器。得到了１０６４ｎｍ和１３１８ｎｍ的激光输出能量分别为０．５９４Ｊ和０．８６１Ｊ，效率分别为０．３１％和０．４５％。实验结果说明了该双波长激光器有较好的时间和空间重选性。

Upon the basis of oscillation condition of simultaneous multiple wavelengthlasing, 1064 urn and 1318 dual wavelength Nd: YAG pulsed laser has been established.The output energies of 0. 594 J and 0. 86 J with efficiencies of 0. 31% and 0. 45% for the1064 urn and 1318 urn respectively have been achieved. From the experimental results, wefound this kind of dual wavelength pulsed laser has a quite gial spetio-temperal overlappingproperty.
