Glass waveguide laser

Abstract

A channel waveguide fabricated in a Nd/sup 3+/-doped laser glass by the ion exchange method is discussed. The device was end-fire pumped by a diode-laser operating at 802 nm. Continuous-wave (CW) lasing was observed at 1054 nm, and maximum output power was higher than 150 mW. The large output power was achieved by increasing the radius of the waveguide.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
