Abstract:
A light emitting device includes a fluorescent material, a first laser element and a second laser element. The first laser element is configured to emit a first laser light to excite the fluorescent material. The first laser light having a first peak wavelength that is shorter than an excitation peak wavelength of the fluorescent material. The second laser element is configured to emit a second laser light to excite the fluorescent material. The second laser light has a second peak wavelength that is longer than the excitation peak wavelength of the fluorescent material.
