diode-pumped laser; high power laser; thermal lensing; Nd:YLF
We report the design and the operation of a novel two-head, side-pumped Nd:YLF laser that generates up to 25 W TEM₀₀ output power at 1.053 μm. The anisotropic thermal lensing of each laser head has been examined and compensated with cylindrical lenses. The output power of this two-head laser exhibits excellent dynamic range with a typical optical–optical conversion efficiency of 18%.
