Paper Abstract

We have developed 2micron Q-switched lasers with conductive-cooled side pumped laser head. Q-switched output of 100mJ at 20Hz has been achieved in a Tm,Ho:YLF laser oscillator with a composite rod. The experiments showed that very good thermal conduction is held between rod and heat sink. This laser head may be used for laser amplifier of 500mJ output. Another type of Tm,Ho:YLF laser head has been developed for the oscillator of 50-100mJ output at 20-40Hz. These 2micron lasers are applied to coherent lidar systems, which will be used to measure atmospheric CO2 and wind profiling.
