摘要： To provide a wavelength tunable laser device having a wavelength variable range of a broad band, and capable of simply changing the output wavelength. Excitation means 1 excites a laser medium 2a in a main resonator 2. The main resonator 2 is provided with two resonator mirrors 2b and an optical input/output port 2c in addition to the laser medium 2a. By the excitation means 1 and the main resonator 2, laser oscillation can be produced. A sub-resonator 3 is provided with wavelength selection means 3a and optical feedback means 3b. And, the sub-resonater selects a desired wavelength of the laser beam outputted from said main resonator and returns the laser beam of the desired wavelength back to said laser medium. In a device comprising the excitation means 1, the main resonator 2 and the sub-resonator 3, an optical output port 4 is provided. Since this wavelength tunable laser device has no necessity of providing wavelength selection means within the main resonator, laser oscillation is easily produced. Accordingly, even in the case where the gain of the laser medium is small, or the excitation energy is small, oscillation can be produced. In addition, since the main resonator can be placed in an oscillating state at all times, the wavelength tunable laser device can be prevented from being stopped.

摘要： An ultrashort pulse laser apparatus of the this invention includes (1) a laser medium, (2) a laser resonator which stores the laser medium and externally extracts a laser beam, and (3) an excitation source for outputting an excitation energy to the laser resonator to excite the laser medium. The laser resonator includes (i) a plurality of resonant mirrors disposed on both sides of the laser medium to form a resonant optical path, and (ii) a phase dispersion compensation unit which includes two optical members respectively arranged on two light input/output surface sides of the laser medium on the resonant optical path and compensates phase dispersion of light in the resonant optical path. That is, the laser medium is disposed in the optical path between the two optical members of the phase dispersion compensation unit. With this arrangement, even when the laser medium is arranged almost at the center of the laser resonator to stabilize mode locking, the cavity length of the resonant optical path can be reduced. Therefore, the repetition frequency of laser pulses can be increased, and simultaneously, size reduction of the laser apparatus itself can be achieved.
