GHz repetition rate, sub-100-fs Ho:CALGO laser at 2.1 um with watt-level average power
Weichao Yao, Mohsen Khalili, Yicheng Wang +4
We report on a GHz fundamental repetition rate Kerr-lens mode-locked Ho:CALGO laser emitting at 2.1 um. The laser employs a ring-cavity to increase the fundamental repetition rate…
