Resumo: The present dissertation successfully characterized a low-finesse Fabry-Perot cavity. The cavity was locally constructed and coupled to a commercial single-frequency laser from QPhotonics. We needed to develop an apparatus to stabilize the mechanical vibrations to realize the experiment. We measured a finesse value of 720 ± 16, a photon lifetime of (50 ± 0.03) ns, a mirror reflectance of 0.9966 ± 0.0006, a quality factor of 8.86 × 107, and a cavity’s linewidth of (4.0 ± 0.7) MHz. Estimating a value for the cavity propagation-loss coefficient of (0.017 ± 0.003) m−1 was also possible.

A cavidade foi construída localmente e acoplada a um laser comercial de frequência única da QPhotonics. Para realizar o experimento, desenvolvemos um aparato de estabilização de vibrações mecânicas. Conseguimos medir um valor de finesse de 720 ± 16, o tempo de vida do fóton de (50 ± 0,03) ns, a reflectância dos espelhos de 0.9966 ± 0.0006, um fator de qualidade de 8,86 × 107 e uma largura de linha de (4.0 ± 0.7) MHz. Também foi possível estimar um valor para o coeficiente de perdas da cavidade em (0,017 ± 0,003) m−1.engUniversidade Federal de PernambucoPrograma de Pos Graduacao em FisicaUFPEBrasil-1https://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessFabry-perotÓpticaMetrologiaCoeficiente de perdaTempo de vida do fótonFinesseCharacterization of a Fabry-Perot Cavity Using a Single-Frequency Laserinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesismestradoreponame:Repositório Institucional da UFPEinstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPEORIGINALDISSERTAÇÃO João Lucas Romão Gomes Daré.pdfDISSERTAÇÃO João Lucas Romão Gomes Daré.pdfapplication/pdf3743435https://repositorio.ufpe.br/bitstream/123456789/63604/1/DISSERTA%c3%87%c3%83O%20Jo%c3%a3o%20Lucas%20Rom%c3%a3o%20Gomes%20Dar%c3%a9.pdf5fa9ca8934ec14f83b837f75daf6a13bMD51LICENSElicense.txtlicense.txttext/plain;
