Green and Jun Ye}, title = {A nozzle for high-density supersonic gas jets at elevated temperatures}, abstract = {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}, year = {2018}, journal = {Review of Scientific Instruments}, volume = {89}, chapter = {113114}, pages = {113114}, month = {2018-01}, issn = {0034-6748}, url = {http://aip.scitation.org/doi/10.1063/1.5051586}, doi = {10.1063/1.5051586}, }
