Abstract

Efficient lasers operating in the 1.3 μm band are of interest in the health industry for frequency conversion to the visible spectral region and for Raman shifting to the eye-safe 1.5 μm region. In this work, we demonstrate for the first time, to our knowledge, a side-pumped Nd:YLiF4 laser emitting at 1.3 μm. An output power of up to 14.9 W was obtained at 1313 nm with 54 W of absorbed pump power, representing 27.7% optical efficiency and a slope efficiency of 45%.
