Abstract
A compact apparatus is provided for stably converting a wavelength of a laser diode with the use of an optical fiber and a wavelength selective device. Employing a bulk type element as a wavelength selective device makes the action of controlling the temperature of the device easy, and can stabilize the wavelength emitted from the laser diode.) of bulk type.) is sufficiently longer than the coherence length. Accordingly, the action of stably converting the wavelength can be carried out by the compact apparatus.
