The design criteria and performance characteristics are reported of a tunable, narrow bandwidth dye laser that is suitable for pumping by a short pulse duration high power N(2) laser. The dye laser system is characterized by a relatively short over-all length of 15 cm. Bandwidths of from 0.015 nm to 0.05 nm are obtained along with conversion efficiencies in the neighborhood of 10% using a 4-5 nsec pulse duration N(2) pump. Bandwidths of 0.001 nm are observed with an intracavity etalon in the system. More important, however, it is shown that the conversion efficiency of an intracavity etalon dye laser system can be greatly improved if the temporal distribution of the N(2) pump pulse is adjusted so a single dye cell in a dye laser system is used first as an oscillator and then as an amplifier. Finally, using the above technique of processing the N(2) pump pulse, a 5-nsec N(2) laser is used to pump an intracavity etalon dye laser, which is followed by a large gap external etalon and then by an amplifier; the resulting bandwidth is 0.0005 nm at 480 nm with a conversion efficiency of 4.5%.
报道了一种可调谐窄带宽染料激光器的设计标准和性能特性，该激光器适用于由短脉冲持续时间的高功率N₂激光器泵浦。该染料激光系统的特点是总长度相对较短，为15厘米。使用4 - 5纳秒脉冲持续时间的N₂泵浦时，可获得0.015纳米至0.05纳米的带宽以及接近10%的转换效率。在系统中使用腔内标准具时，观察到带宽为0.001纳米。然而，更重要的是，如果调整N₂泵浦脉冲的时间分布，使得染料激光系统中的单个染料池先用作振荡器，然后用作放大器，腔内标准具染料激光系统的转换效率可以大大提高。最后，使用上述处理N₂泵浦脉冲的技术，用5纳秒的N₂激光器泵浦腔内标准具染料激光器，随后是大间隙外腔标准具，然后是放大器；在480纳米处得到的带宽为0.0005纳米，转换效率为4.5%。
