脉冲染料激光腔与输出能量、谱线宽度的关系

依照调谐元件和腔结构参数来计算激光输出线宽、单脉冲输出能量,并由此来选择激光器的结构设计。文内叙述的理论与实验一致,并给出了MTGM腔与MGM腔实验数据的对比,本文对脉冲染料激光器的设计有指导意义。     

HIGH ENERGY Xe~+ ENHANCED ADHESION OF Al AND Ag FILMS ON OPTICAL GLASS

The samples consisting of 100nm Al or Ag film on optical glass substrate were irradiated by a beam of Xe 5×10~(15) to 2×10~(16) cm~(-2) with energy 320 keV. The adhesion of films on substrates was tested by Xe~+ irradiation. Optical character was measured by spectrophotometer. The ion mixing amount was measured by RBS. The results showed that after ion irradiating the adhesion of the film on the glass is enhanced. The adherent strength is greater than 10 kg/cm~2. The thermal stability of the films is good. The irradiated film is more optically efficient, the surface is smooth and rendered more corrosion resistance. The mechanism of the film adhesion was discussed.

碳的束箔光谱、能级寿命和跃迁几率

碳离子是高温等离子体中主要的杂质之一,在用光学方法测定高温等离子体中杂质浓度和分布时能级寿命参数带来很大的不确定性和误差。我们将用束箔光谱方法对高温等离子体有关杂质光谱能级寿命和跃迁几率进行研究,这里只给出碳的束箔光谱研究的初步结果。     

Tm~(3+):LaF_3晶体的双光子跃迁

用YAG激光二次谐波泵浦的染料激光器激发Tm~(3+):LaF_3晶体,观察到了~3H_6至~1I_6能级的双光子吸收造成的紫外荧光。用染料激光的二倍频激发样品,获得了~1I_6能级的荧光谱,并测量了相对强度以及~1I_6和~1G_4能级的寿命。利用荧光相对强度拟合了Tm~(3+):LaF_3晶体的Ω参数,
