1. A gas turbine combustor, comprising:
a casing;
a combustion cylinder which is provided in the casing and is configured to combust fuel and oxidant to produce combustion gas;
a pipe-shaped member provided to penetrate the casing and the combustion cylinder;
a heat-resistant glass which is provided on the casing side in the pipe-shaped member and disposed to close the pipe-shaped member;
a laser light supply configured to irradiate an interior of the combustion cylinder through the heat-resistant glass and an interior of the pipe-shaped member with a laser light; and
a contact prevention mechanism configured to prevent the combustion gas in the combustion cylinder from coming into contact with the heat-resistant glass,
wherein the pipe-shaped member has an outside projecting portion projecting to an outside of the casing; and
the contact prevention mechanism comprises:
an annular member which is provided on an outer periphery of the outside projecting portion over a circumferential direction and includes an annular passage;
a fluid supply part configured to supply a fluid to the annular passage; and
an ejection part which has a plurality of ejection holes formed in a circumferential direction of the outside projecting portion and is configured to eject the fluid supplied to the annular passage through the ejection holes into the pipe-shaped member.
