Multi-watt high efficiency diffraction limited Nd: YAG planar waveguide laser

Multi-watt high efficiency diffraction limited Nd: YAG planar waveguide laser
Multi-watt high efficiency diffraction limited Nd: YAG planar waveguide laser
An efficient, longitudinally diode-pumped, diffraction-limited, Nd:YAG double-clad planar waveguide laser was operated on four transitions of the Nd3+ ion. Optimised output powers of 4.3W, 3.5W, and 2.7W, were obtained for absorbed pump powers of ~7W, for the transitions at the lasing wavelengths of 1.064µm, 946nm, and 1.3µm, respectively. Operation of the weak 4F3/2 to 4I15/2 transition, lasing at 1.833µm, was demonstrated at an absorbed pump power threshold of 300mW and an output power of 400mW, with a non-optimised output coupling. Diffraction-limited performance was obtained in both the guided and non-guided axes.

Abstract

An efficient, longitudinally diode-pumped, diffraction-limited, Nd:YAG double-clad planar waveguide laser was operated on four transitions of the Nd3+ ion. Optimised output powers of 4.3W, 3.5W, and 2.7W, were obtained for absorbed pump powers of ~7W, for the transitions at the lasing wavelengths of 1.064µm, 946nm, and 1.3µm, respectively. Operation of the weak 4F3/2 to 4I15/2 transition, lasing at 1.833µm, was demonstrated at an absorbed pump power threshold of 300mW and an output power of 400mW, with a non-optimised output coupling. Diffraction-limited performance was obtained in both the guided and non-guided axes.
