  • Patent number: 9634769
    Abstract: A robust broadband ASE (amplified spontaneous emission) fiber light source device outputs a light beam which is little affected by temperature and radiation. The light source device is a single-pass backward or double-pass backward architecture, and has a coolerless pump laser and temperature compensated bandpass reflector. The light source device may have a high pass filtering element disposed between the wavelength division multiplexer thereof and the optical isolator thereof, so as to compensate the effect of the temperature to the mean wavelength of the light beam. The specific band of the temperature compensated bandpass reflector which reflects the light beam, and the band which the high pass filtering element transmits the light beam are within the band which the ASE unit amplifies the light beam, and the high pass filtering element mainly absorbs the light beam outside the specific band.

  • Publication number: 20120033688
    Abstract: The present invention provides a single frequency fiber laser apparatus. The fiber laser apparatus includes a Faraday rotator mirror. A piece of erbium doped fiber is inside the laser cavity. A wavelength selective coupler is connected to the erbium doped fiber. A pump source is coupled via the wavelength selective coupler. At least one sub-ring cavity component and/or an absorb component are inserted into the cavity for facilitating suppressing laser side modes to create a single longitudinal mode fiber laser. A partial reflectance fiber Bragg grating (FBG) is used as the front cavity end for this fiber laser.

  • Publication number: 20040191344
    Abstract: A pharmaceutical composition for the prophylaxis and treatment of osteoporosis is provided. The composition is extracted from a mixture including Semen cuscutae, or Fructus cindii and Semen cuscutae, and then purified to obtain a large amount of active ingredients, such as coumarins and flavanoids. The pharmaceutical composition made from Semen cuscutae only is also effective. The aforesaid pharmaceutical composition can also be used with calcium and/or vitamin D3.
