The laser driving the mod 0) to mod 1) transition is intense, whilst the laser connecting the mod 1) to mod 2) transition is weak. In addition, a squeezed vacuum field is centered on the mod 0) to mod 1) transition. They calculate the optical double resonance spectrum for this system, and show that it depends very sensitively on the squeezing phase and degree of squeezing. Normally the ODR spectrum consists of two peaks, but when the population trapping condition of Courty and Reynaud (1989) is satisfied, one of the peaks disappears. The observation of the ODR spectrum could provide a means of detecting a squeezed field.","PeriodicalId":130003,"journal":{"name":"Quantum Optics: Journal of The European Optical Society Part B","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115242064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
