A Two-micron Non-planar Ring Oscillator (NPRO) Laser

ORAL

Abstract

Future cryogenic gravitational-wave detectors, such as LIGO Voyager and the Einstein Telescope, plan to use crystalline silicon as the test mass material. These detectors will require a longer laser wavelength in order to transmit the laser light through the silicon. Here, we report results from a Ho:YAG (holmium-doped yttrium aluminum garnet) NPRO oscillator that successfully lases with a wavelength of about 2.1 μm. The oscillator uses a thulium fiber laser operating at a 1.908 μm wavelength as the pump beam. We observe up to 880 mW output power in CW operation.
