The special frequency stabilization is based on the accurate control of the intensity tuning curve in the prism ring laser. In this study, the effects of the ratio of the Ne isotopes, the inflation pressure, and the frequencies coupling on the intensity tuning curve in a laser gyro were examined. The profiles of the intensity tuning curve were simulated under the mixing ratios of Ne20 and Ne22 of 1:1 and 7:3, and the inflation pressures were 350 Pa, 400 Pa, and 450 Pa. The mixing ratio of Ne20 and Ne27 was dealt with similarly. The method for precisely adjusting the profiles of the intensity tuning curve was analyzed. The profiles were verified by experiments under different isotope ratios and pressures. Finally, based on a prism ring laser with an optical length of 0.47 m, the proposed frequency stabilization method was preliminarily verified.<\/jats:p>","DOI":"10.3390\/s22166300","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T05:18:17Z","timestamp":1661145497000},"page":"6300","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Study of the Steady-State Operation of a Dual-Longitudinal-Mode and Self-Biasing Laser Gyroscope"],"prefix":"10.3390","volume":"22","author":[{"given":"Jianning","family":"Liu","sequence":"first","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2032an University of Technology, Xi\u2032an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7123-618X","authenticated-orcid":false,"given":"Jun","family":"Weng","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2032an University of Technology, Xi\u2032an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junbiao","family":"Jiang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Modern Control Technology, Xi\u2019an 710065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yujie","family":"Liu","sequence":"additional","affiliation":[{"name":"Wingtech Mobile Communications Co., Ltd., Xi\u2019an 710000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingxing","family":"Jiao","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2032an University of Technology, Xi\u2032an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2032an University of Technology, Xi\u2032an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2032an University of Technology, Xi\u2032an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Filatov, Y.V., Pavlov, P.A., Velikoseltsev, A.A., and Schreiber, K.U.
