PROBLEM TO BE SOLVED: To provide a pulsed laser oscillator which suppresses heat generation in a host crystal, can be miniaturized, has excellent thermal durability, and can obtain an output beam of high quality and high output. SOLUTION: The pulsed laser oscillator concerning this invention includes a conical lens 10 which makes the pumping light generated by a pumping light source 2 into a Bessel beam and makes it incident on a solid laser medium 5. The solid laser medium 5, an aperture 7 and the host crystal 6 are integrally bonded together, and direct bonding is carried out between the solid laser medium 5 and the aperture 7, and between the aperture 7 and the host crystal 6.
