PROBLEM TO BE SOLVED: To provide a laser probe which enables evenly jetting of a mixture of a liquid and a gas over the entire circumference of a probe fiber with a relatively simple structure. SOLUTION: This laser probe is provided with a probe holder 58 to be mounted on the body of a hand piece, a probe fiber 60 mounted on the probe holder 58, a first tube member 70 covering a part of the probe fiber 60 and a second tube member 72 covering the first tube member 70. A first passage 74 for supplying a liquid is formed between the probe fiber 60 and the first tube member 70, a second passage 76 for supplying a gas is formed between the first tube member 70 and the second tube member 72, and the liquid and the gas are mixed and jetted toward a part to be irradiated with a laser light being atomized. The first tube member 70 is provided with a concentric holding part 70a to hold the first and second tube members 70 and 72 concentrically on the probe fiber 60. |
