Feedback Control of a Tunable Laser for Cavity Optomechanics
公开可下载的内容
open in viewerThe team developed a LabVIEW-based software for feedback control of a New Focus 6700 Tunable Laser System. By controlling motor scan of the laser cavity in the wide range and piezo scan in the narrow range, the wavelength tuning of the laser was fully controlled by the developed software with a resolution in picometers. More importantly, the team built a fiber-based Mach-Zehnder interferometer to both measure the laser wavelength and sense strain and stress. To demonstrate the developed control system, a microscale cavity optomechanical device was optically characterized. By coupling light through a micrometer-sized fiber taper into the device while monitoring the optical transmission power, the developed system enabled the measurements of high optical quality factor of the device.
