Disclosed is a laser apparatus capable of performing multi-output. The laser apparatus comprises: a first resonator configured to oscillate optically pumped first excitation light; a second resonator configured to oscillate second excitation light having a different pulse width from the first excitation light; and an optical amplifier equipped in oscillating paths of the first and second excitation light, and optically pumping the first and second excitation light to be amplified. Accordingly, laser light having two types of pulse widths oscillated from each resonator generating two types of pulse widths are amplified through one amplifier, so the present invention can provide the miniaturized laser apparatus which can be generally used. Also, the resonators and the amplifier are disposed so that the output direction of the resonators and the output direction of the amplifier can be symmetrical, so the present invention can provide the laser apparatus having smaller size and structure. In addition, the laser apparatus variously changes wavelengths of laser light having two types of pulse widths outputted through the amplifier, thereby increasing generality and compatibility of the laser apparatus. |
