Abstract:
A light emitting device includes a semiconductor laser element; a cap defining a through-hole allowing light from the semiconductor laser element to pass therethrough; and a wavelength converting member disposed in the through-hole defined in the cap, the wavelength converting member being configured to emit light that has a wavelength different from a wavelength of light from the semiconductor laser element. The cap includes a first member made of a ceramic, and a second member made of a metal material. The through-hole includes a first through-hole penetrating the first member, and a second through-hole penetrating the second member. The wavelength converting member is disposed on the second member.
