TY - JOUR AU - Christoph Heyl AU - Stephen Schoun AU - Gil Porat AU - H. Green AU - Jun Ye AB - We have demonstrated a high-temperature glass nozzle capable of delivering a high-density supersonic gas jet close to the focus of a high-power laser beam. The nozzle can simultaneously handle temperatures of 730 °C and backing pressures of 124 bars. Continuous operation of this nozzle over many hours inside a delicate optical resonator placed in a vacuum environment was demonstrated, enabling the generation of coherent radiation at 12.7 eV with record average power around 2 mW.9 BT - Review of Scientific Instruments DA - 2018-01 DO - 10.1063/1.5051586 N2 - We have demonstrated a high-temperature glass nozzle capable of delivering a high-density supersonic gas jet close to the focus of a high-power laser beam.
