Through significant development, this laser system is now capable of generating &gt; 1 W of stable UV power over hour long time scales. We are able to control the frequency of this radiation precisely, enabling 2-photon excitation of the 1S-2S transition in hydrogen. With this system, we plan to excite a large number of cyrogenic hydrogen atoms to the 2S state in hydrogen in a UV enhancement cavity, where we can then perform 2S-8D spectroscopy. Once this is complete, the powers built up in this deep UV enhancement cavity can be used to demonstrate two-photon laser cooling of hydrogen.<\/p>\n<p>You can find the full version of the paper here<\/p>\n<p><a href=\"https:\/\/www.osapublishing.org\/ao\/abstract.cfm?uri=ao-58-7-1657\">https:\/\/www.osapublishing.org\/ao\/abstract.cfm?uri=ao-58-7-1657<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We recently published an article in Applied Optics on our 243.1 nm laser system.
