| A study of the performance of the Nd+3 : POCl3 : ZrCl4 liquid laser system is presented. Its properties are described and compared with those of other neodymium lasers. An evaluation of the potentialities of this system as an actively Q-switched oscillator and as a high power amplifier is made. The generation and amplification of picosecond pulses in neodymium laser systems are reviewed. Frequency shifts in broad band amplifiers have been observed and their effect on the power gain has been investigated. |
