Abstract

See full text

A light absorbing layer which is bonded to a laser medium to configure a bonded body, wherein the light absorbing layer is formed from a glass material and, in an oscillation wavelength (wavelength of 650 nm or more and less than 1400 nm) of the laser medium, an absorption coefficient is 0.1 to 10.0 cm−1, a difference in refractive index between the light absorbing layer and the laser medium is within ±0.1, and a difference in linear thermal expansion coefficient between the light absorbing layer and the laser medium is within ±1 ppm/K. The present invention relates to a light absorbing layer for preventing parasitic oscillation, and aims to provide a material capable of suppressing the manufacturing cost and which can be easily processed for preparing a bonded body.
