“…The main reason for the lower thermal stress in b-cut Tm: YAP, as compared to a-cut Tm: YAP, is the smaller thermal expansion coefficient of the former. All these values are below the fracture threshold of 160 MPa [14], thereby minimizing the risk of fracturing into the slab. The experimental setup of the Ho: YAG laser intracavity-pumped using an LD-pumped Tm: YAP laser is depicted in Fig.…”

We demonstrated a compact and efficient Ho:YAG slab laser intra-cavity pumped by a Tm:YLF slab laser for the first time. In the Tm:YLF laser operation, the maximum power of 32.1 W with optical-to-optical efficiency of 52.8% was obtained. In the intra-cavity pumped Ho:YAG laser operation, the output power of 12.7 W at 2122 nm was obtained. The beam quality factors M2 in the vertical and horizontal directions were 1.22 and 1.11, respectively. The RMS instability was measured to be lower than 0.1%. To the best of our knowledge, this was the maximum power for the Tm-doped laser intra-cavity pumped Ho-doped laser with near-diffraction-limited beam quality.
