Investigation of Narrowband Acousto-Optic Tunable Filters for Semiconductor Laser Tuning
… tunable sources find applications in areas of laser surgery, optical coherence tomography, material processing, and differential absorption light detection and ranging. Acousto-optic tunable filters (AOTFs) are wavelength selective devices which allow for better stability than mechanical tuning …

Whispering gallery mode microcavities: from fabrication to applications
… topics as diverse as optomechanics, photonics, laser tuning and spectroscopy. The WGMs in the microsphere pendulum sense its mechanical mode through fibre taper coupling of light. Its properties in the evanescent light fields and its optomechanical transduction characteristics were investigated. …

Gravity Waves Studies in Mesopause Region by Using Na Wind/temperature Lidar
… temperature, and all three wind components. The laser tuning technique is improved. To make the lidar capable of measuring horizontal wind, the mirror mounting is integrated into the lidar system, and software is written to control the mirror mounting and to communicate with the telescope …

Analyse optischer Heterodynsignale zur dynamischen Charakterisierung von Diodenlasern
Die stetige Degradation von Halbleiterlasern, speziell bei Bleichalkogenidlasern, erfordert in spektroskopischen Systemen eine regelmäßige Überwachung typischer Eigenschaften wie Abstimmcharakteristik und Linienbreite. Im Hinblick auf einen möglichst hohen Automatisierungsgrad wird langfristig eine …
