    Abstract: The present disclosure is related to a fluorescent glass for a light emitting diode and a manufacturing method thereof. The fluorescent glass for the light emitting diode includes a glass powder and a fluorescent powder, wherein the glass powder and the fluorescent powder are mixed to form a fluorescent glass, the material for manufacturing the glass powder comprises silicon dioxide with 20 wt % to 37 wt %, diboron trioxide with 31 wt %-47 wt % and calcium oxide with 16 wt %˜35 wt %, and the material of the fluorescent powder is selected from one of Ce-YAG, LuAG, silicate, and nitrides/oxynitrides fluorescent powder. The fluorescent glass of the present disclosure is formed by mixing and sintering the glass powder and the fluorescent powder and has low sintering temperature, so as to avoid the deterioration of color of the fluorescent powder due to high temperature. Therefore, the fluorescent glass of the present disclosure has good transparency, and the light emitting diode applying this fluorescent glass has good lighting efficiency.

    Abstract: An optical isolator for generally collimated laser radiation includes a single polarizing element, at least one Faraday optical element, at least one reciprocal polarization altering optical element disposed at the single polarizing element, at least one reflective optical element for reflecting radiation to provide an even number of passes through the at least one Faraday optical element, and a magnetic structure. The magnetic structure is capable of generating a magnetic field within the at least one Faraday optical element that is generally aligned with the even number of passes along a beam propagation axis. The optical isolator is configured to receive generally collimated laser radiation, which passes through the single polarizing element and the at least one reciprocal polarization altering optical element and which makes at least two passes through the at least one Faraday optical element, whereby generally collimated laser radiation is output from the optical isolator.
