摘要 |
The present invention relates w a wavelength-convertible semiconductor laser which is driven by a pulse, and more specifically, to a wavelength-convertible semiconductor laser, wherein: an expanded resonator is formed by including a laser diode chip on the outside of a pump semiconductor laser diode chip; and an oscillating wavelength of a pump laser is driven by a pulse determined from the outside of the semiconductor laser diode chip by inserting a filter, which is capable of selecting a wavelength, on the inside of said expanded resonator.
