碩士 === 逢甲大學 === 光電物理研究所 === 95 === The thesis aims to stabilize the frequency of a 1530 nm external cavity tunable diode laser on the homemade high finesse Fabry-Perot cavity. Using error singal from Pound-Drever-Hall scheme to feedback to the pzt of external cavity laser, the laser is stabilized on the resonance frequency of Fabry-Perot cavity. We lock the frequency of laser to the cavity under vacuum condition down to the pressure of 22 Torr successfully. In the future, we will fill the cavity with acetylene gas to carry out the cavity enhanced absorption for the observation of saturated absorption of R(8) transition of line of acetylene.
