While the project remains ongoing, significant progress has been\r\nmade.\r\nA key contribution of this work is the development of Quantrol, an experimental control\r\nsystem leveraging the ARTIQ framework. This software enables precise timing and control\r\nwithout requiring prior knowledge of ARTIQ’s implementation details or coding experience.\r\nThe interface offers user friendly visual comprehension of the experimental sequence and\r\nextended capabilities, allowing researchers to scan variables with a simple click of a mouse.\r\nThe main proposed project is to implement atom interferometric sequence with squeezed input\r\nstates inside of a dipole trap generated by a high finesse cavity. The presence of the dipole\r\ntrap allows one dimensional atomic cloud split while maintaining relatively strong confinement\r\nin other directions.\r\nWe are currently able to trap and cool 87Rb atoms to few micro kelvin temperatures, load\r\nthem into the dipole trap and state prepare them to be used for squeezing and interferometric\r\nsequence.","lang":"eng"}],"publication_identifier":{"issn":["2663-337X"]},"fulldoi":"https://doi.org/10.15479/at:ista:17225","related_material":{"record":[{"id":"11438","relation":"part_of_dissertation","status":"public"}]},"file":[{"date_created":"2024-07-11T10:26:22Z","relation":"main_file","file_name":"PhD_Thesis_Vyacheslav_Li_no_signatures_PDFA.pdf","content_type":"application/pdf","creator":"vli","access_level":"open_access","file_id":"17228","file_size":6729761,"checksum":"15b2dbe8d2c9ed7ca5dd413827928077","success":1,"date_updated":"2024-07-11T10:26:22Z"},{"content_type":"application/x-zip-compressed","creator":"vli","file_id":"17229","access_level":"closed","date_created":"2024-07-11T10:26:22Z","relation":"source_file","file_name":"PhD Thesis Vyacheslav Li.zip","date_updated":"2024-07-11T10:26:22Z","checksum":"16e904a11d8d0ebb167cb654ddfc7fe5","file_size":9542859}]},{"type":"journal_article","isi":1,"issue":"15","department":[{"_id":"OnHo"}],"year":"2023","publication_status":"published","language":[{"iso":"eng"}],"user_id":"68b8ca59-c5b3-11ee-8790-cd641c68093d","doi":"10.1364/ol.495553","publisher":"Optica Publishing Group","citation":{"mla":"Mishra, Umang, et al. “Monitoring and Active Stabilization of Laser Injection Locking Using Beam Ellipticity.” <i>Optics Letters</i>, vol. 48, no. 15, Optica Publishing Group, 2023, pp. 3973–76, doi:<a href=\"https://doi.org/10.1364/ol.495553\">10.1364/ol.495553</a>.","chicago":"Mishra, Umang, Vyacheslav Li, Sebastian Wald, Sofia Agafonova, Fritz R Diorico, and Onur Hosten. “Monitoring and Active Stabilization of Laser Injection Locking Using Beam Ellipticity.” <i>Optics Letters</i>.

The presented demonstration locks two free-running diode lasers at 780 nm with a 5.5-GHz offset. It displays an offset frequency instability below 55 Hz for time scales in excess of 1000 s and a minimum of 12 Hz at 10-s averaging. The performance is complemented with a 190-MHz lock-capture range, a tuning range of up to 1 GHz, and a frequency ramp agility of 200kHz/μs.","lang":"eng"}],"fulldoi":"https://doi.org/10.1103/physrevapplied.17.054031","related_material":{"record":[{"status":"public","id":"17225","relation":"dissertation_contains"}]},"das_tickbox":"0","acknowledgement":"This work was supported by IST Austria.
