Abstract

In this paper we describe the design and performance characteristics of a diode-laser-pumped, cw, NdrYLF laser with intracavity second harmonic generation (SHG). We include descriptions of the micro-optics used to couple pump power from a 10-W diode laser to the Nd:YLF crystal in an end-pumped configuration; the opto-mechanical design of the Nd:YLF gain element; the performance of the Nd:YLF laser at 1047 nm; and the design and performance of resonators configured for intracavity SHG with both KTP (II) and LBO (I) crystals. The highest output power obtained to date, with an LBO SHG crystal, was 1.25 W at 523.5 nm.
