IEEE Photonics Technology Letters, 2016•ieeexplore.ieee.orgA diode-side-pumped laser oscillator with a Tm, Ho: YLF rod conductively cooled to-80° C
was developed. A Q-switched pulse energy of 104 mJ was achieved at a pulse repetition
frequency of 70 Hz, corresponding to an average output power of 7.28 W. In addition, the
maximum Q-switched pulse energy of 125 mJ was obtained at 50 Hz. Even at the maximum
output level, the beam quality factor M 2 was measured to be≤ 1.5. To the best of our
knowledge, this is the highest average output power reported for a 100-mJ-class Q-switched …

To the best of our knowledge, this is the highest average output power reported for a 100-mJ-class Q-switched 2-μm laser oscillator using a conductively cooled laser head.
