This invention relates to a solid laser device with a slab-shaped laser medium. One example of a solid laser device according to the invention, comprises: a slab-shaped laser medium having one pair of optically smooth surfaces confronting each other through the optical path; first and second mirrors arranged on the optical path in such a manner that the first and second mirrors are confronted with each other through the laser medium; a resonator which forms an unstable resonator in the direction of width of the laser medium, and a low order stable resonator in the direction of thickness of the laser medium; and laser beam emergence medium for taking a laser beam out of the a resonator and outputting the laser beam from the device. Another example comprises: a slab-shaped laser medium having a pair of optically smooth surfaces confronting each other through the optical path; first and second mirrors arranged on the optical path in such a manner that the first and second mirrors are confronted with each other through the laser medium; a resonator which forms unstable resonators in the direction of width of the laser medium and in the direction of thickness of the same; and laser beam emergence medium for taking a laser beam out of the a resonator and outputting the laser beam from the device. Accordingly, the solid laser devices can output a high power laser beam excellent in convergence, thus being applicable to precision laser machining operations.
