IPC: H01S3/17
Filed: 1990-04-12
Abstract: PURPOSE:To realize continuous oscillation at room temperature by opposing two reflectors through an active medium containing laser active ions and composing the active medium of a fluoride glass fiber. CONSTITUTION:In an optical fiber type laser comprising two reflectors opposing through an active medium containing laser active ions, the active medium is composed of a fluoride glass fiber 2 containing less than 1mol% of TmF3. Upon pumping with the beam from a semiconductor laser diode 4, light is spontaneously emitted in the fluoride fiber 2 to which Tm is added and temporarily converted through an objective lens 6' into a parallel beam which is then passed through a half mirror 5 and impinged on a grating 3. Light having specific wavelength is selectively returned through the grating 3 to the fluoride fiber 2 to which Tm is added and reflected on the mirror 1 thus constituting an optical feedback system. Consequently, semiconductor pumping and continuous oscillation at room temperature are realized.

Abstract: PURPOSE:To set conditions of heat treating a substrate of a susceptor effectively in a satisfactory state by bringing a fluorescent type fiber thermometer into contact with a position isolated from a placing unit of the substrate, and calculating a board temperature from the result of the measured temperature. CONSTITUTION:A sensor 3a of a fluorescent type fiber thermometer 3 is disposed at a position isolated from a substrate placing unit of a susceptor 2 to measure its temperature. That is, the relationship between the detected temperature of the thermometer 3 and actual board temperature is measured, and the temperature of the substrate 1 is calculated based on the temperature measuring result.
