High-power operation of an intracavity-pumped Ho:YAG laser at 2.1 μm

High-power operation of an intracavity-pumped Ho:YAG laser at 2.1 μm
High-power operation of an intracavity-pumped Ho:YAG laser at 2.1 μm
The setup for the intracavity-pumped laser is similar to the Tm:YAG lasers. The 45-nm-long linear cavity has a pump input mirror having high reflectivity from 2.0-2.1 μm. The output coupler is highly reflective from 2.00-2.02 μm with 10% transmission around 2.1 μm. Both the Tm:YAG rod and the 10-nm-long 0.5%-doped Ho-YAG rod were mounted on the same water cooled heat sink maintained at 10 °C. The shaped beam from the diode pump was focused to a spot of 300 μm diameter. The threshold for Tm:YAG lasing was 1.5 W, while the Ho:YAG started lasing at the slightly higher diode power of 1.7 W.

Abstract

The setup for the intracavity-pumped laser is similar to the Tm:YAG lasers. The 45-nm-long linear cavity has a pump input mirror having high reflectivity from 2.0-2.1 μm. The output coupler is highly reflective from 2.00-2.02 μm with 10% transmission around 2.1 μm. Both the Tm:YAG rod and the 10-nm-long 0.5%-doped Ho-YAG rod were mounted on the same water cooled heat sink maintained at 10 °C. The shaped beam from the diode pump was focused to a spot of 300 μm diameter. The threshold for Tm:YAG lasing was 1.5 W, while the Ho:YAG started lasing at the slightly higher diode power of 1.7 W.
