Efficient operation of a Nd:YAG laser on the low-gain 1123nm transition by end pumping with the reshaped output from a 7W diode bar is reported. Using a simple standing-wave laser configuration and pumping with 5.6W of incident power yielded a laser output power of 1.7W in a near-diffraction-limited TEMoo mode with a beam quality factor of M2 < 1.1. A unidirectional single-frequency ring laser was also constructed, yielding 180mW of single-frequency output. The prospects for further increase in power by optimization of the resonator design are discussed.

Abstract

Efficient operation of a Nd:YAG laser on the low-gain 1123nm transition by end pumping with the reshaped output from a 7W diode bar is reported. Using a simple standing-wave laser configuration and pumping with 5.6W of incident power yielded a laser output power of 1.7W in a near-diffraction-limited TEMoo mode with a beam quality factor of M2 < 1.1. A unidirectional single-frequency ring laser was also constructed, yielding 180mW of single-frequency output. The prospects for further increase in power by optimization of the resonator design are discussed.
