In a solid-state laser device having an excitation part that irradiates excitation light and a laser rod that receives and excites the excitation light and outputs it as laser light, the laser rod is composed of neodymium ions (Nd 3+ ). A filter section is provided between the excitation section and the laser rod, and the filter section is configured to absorb the excitation light out of the excitation light. A solid-state laser device characterized in that transient absorption of the laser rod is suppressed and sensitized by cutting ultraviolet rays having a wavelength of 330 nm or less. 2. A solid-state laser having a box-shaped body defining a space in which an excitation part that irradiates excitation light and a laser rod that receives the excitation light and outputs it as a laser beam has a reflective surface that reflects the excitation light and makes it incident on the laser rod. A solid-state laser device, wherein the box body has plating on the reflective surface that reflects ultraviolet rays.
