Abstract

A resonantly pumped, trivalent thulium ion (Tm3+) doped, crystal laser with improved efficiency is disclosed. Embodiments are pumped from the 3H6 ground state manifold to the 1st excited 3F4 state manifold by photons with wavelengths between 1.4 and 2.2 microns and laser wavelengths ranging from 1.5 to 2.4 microns arising from 3F4 to 3H6 transitions ensue, with output wavelengths dependant upon the choice of pump wavelength, crystalline host, and resonator optics.
