An efficient 2 μm room temperature Ho: YVO 4 laser resonantly pumped by a 1.94 μm Tm:YAP laser is demonstrated, for the first time to our knowledge, in this Letter. Up to 8.58 W of laser output at 2053 nm is obtained with the optical-to-optical conversion efficiency as much as 41.2%. The output beam had quality of M 2 factor with M x 2 of 3.58 and M y 2 of 1.76 at 8 W output level. In addition, we also obtained 4.18 W laser output at 2066 nm and 7.04 W at 2040 nm from the Ho: YVO 4 laser with conversion efficiency of 27.8% and 33.8%, respectively.
