Title (EN) OPTICAL WAVELENGTH CONVERTER AND COMPOSITE OPTICAL DEVICE

Abstract:
(EN) The present invention provides an optical wavelength converter and a composite optical device that have excellent heat dissipation characteristics and optical wavelength conversion characteristics. An optical wavelength converter 1 has a structure where a heat dissipation member 13 having excellent heat dissipation characteristics is bonded to an optical wavelength conversion member 9, thereby efficiently dissipating heat generated by light incident on the optical wavelength conversion member 9. Therefore, even when higher energy light is incident thereon, temperature quenching is less likely to occur, thereby allowing a higher fluorescence intensity to be maintained. The optical wavelength converter 1 further includes an intermediate film 21 between a reflective film 19 and a bonding part 15. This structure improves the bond between the reflective film 19 and the bonding part 15 to thus improve heat dissipation from the optical wavelength conversion member 9 to the heat dissipation member 13. Consequently this suppresses the temperature quenching of the optical wavelength conversion member 9, thereby improving the fluorescence intensity.
(FR) La présente invention concerne un convertisseur de longueur d'onde optique et un dispositif optique composite qui présentent d'excellentes caractéristiques de dissipation thermique et caractéristiques de conversion de longueur d'onde optique. Un convertisseur de longueur d'onde optique 1 a une structure dans laquelle un élément de dissipation thermique 13 ayant d'excellentes caractéristiques de dissipation thermique est lié à un élément de conversion de longueur d'onde optique 9, dissipant ainsi efficacement la chaleur générée par la lumière incidente sur l'élément de conversion de longueur d'onde optique 9. Par conséquent, même lorsqu'une lumière d'énergie supérieure est incidente sur celui-ci, une chute de température rapide est moins susceptible de se produire, ce qui permet de maintenir une intensité de fluorescence plus élevée. Le convertisseur de longueur d'onde optique 1 comprend en outre un film intermédiaire 21 entre un film réfléchissant 19 et une partie de liaison 15. Cette structure améliore la liaison entre le film réfléchissant 19 et la partie de liaison 15 afin d'améliorer ainsi la dissipation thermique de l'élément de conversion de longueur d'onde optique 9 vers l'élément de dissipation thermique 13. Par conséquent, on supprime la chute de température rapide de l'élément de conversion de longueur d'onde optique 9, ce qui permet d'améliorer l'intensité de fluorescence.
(JA) 放熱特性に優れ、しかも、光波長変換特性に優れた光波長変換装置及び光複合装置を提供すること。光波長変換装置1は、光波長変換部材9に放熱性に優れた放熱部材13を接合する構成により、光波長変換部材9に入射する光によって発生する熱を効率良く放熱できる。そのため、高いエネルギーの光が入射しても、温度消光が生じにくいので、高い蛍光強度を維持することができる。また、反射膜19と接合部15との間に中間膜21を備えている。そのため、反射膜19と接合部15との接合性が向上するので、光波長変換部材9側から放熱部材13側への放熱性が向上する。これにより、光波長変換部材9の温度消光を抑制できるので、蛍光強度が向上する。
