  pulse pumping
For pulse pumping, we show the possibility for forming response-luminescence pulses with widely variable characteristics: shape, duration, intensity, and delay.
      
Production of stimulated emission with double-pulse pumping
      
By changing the interaction phase between the excited coherences and the broadband light field, the coherence was controlled in the double-chirped-pulse pumping scheme.
      
In normal pulse pumping operation, the lasing threshold changed greatly from 122?mJ to 2.4?mJ as the pump pulse frequency varied from 1?Hz to 500?Hz due to pumping-induced thermal effect.
      
A method has been devised which employs double-pulse pumping of the laser rod as a means to substantially reduce this jitter.

Based on discrete algorithm of propagation-rate equation,the ASE dynamic behavior of Er~(3+)/Yb~(3+) co-doped double-clad fiber amplifier under both continuous and pulse pumping is studied.The reason for different change of the ASE output power with time is analyzed as well.The results show that the time and output power value of ASE reaching steady state under continuous pumping depend on the pump power,and the increase of ASE output power corresponds to the decrease of the inverted population of Er~(3+).This study also shows that the length of the fiber under pulse pumping affects significantly the saturation of the forward ASE output power,but does not affect that of the backward ASE output power.

基于速率方程的离散算法,对连续和脉冲泵浦下的双包层Er3+/Yb3+共掺光纤放大器ASE动态特性进行了研究,对ASE随时间呈现不同变化的原因进行了分析。结果表明:连续光泵浦下,双包层Er3+/Yb3+共掺光纤放大器ASE达到稳态的时间和输出功率的大小依赖于泵浦功率,ASE输出功率的增加与Er3+上能级粒子数的减少相对应;脉冲光泵浦下,光纤长度对正向ASE输出功率的饱和存在显著的影响,但不影响反向ASE输出功率的饱和。

>=The transient thermal-optical distortion in the Nd:YAG laser rod repeat pulse-pumped by high power ring-LD array has been simulated in detail by using ray tracing method and finite element method.

从高功率环形LD阵列的发光特性出发,用光线追迹法和有限元方法计算得到高功率激光二极管阵列重复脉冲抽运棒状激光器在线偏振状态工作下的瞬态热畸变。计算结果表明,重复脉冲抽运时,由于冷却不充分,棒内残余温度的不断积累导致热致光程差随时间周期性变化,且逐渐增大到稳定重复状态。一方面,稳定热致光程差随着占空比的增大而增加;另一方面,若占空比相同,热致光程差将随频率的增加而降低;若脉宽相同,它将随频率的增加而增加。采用本文的计算结果,可以定量分析高功率环形LD重复脉冲抽运激光器棒内的瞬态热致畸变。
