Development of high‐power chemical oxygen‐iodine laser for industrial application

A scaling up of kW‐class chemical oxygen‐iodine laser (COIL) is achieved. The key issues for the system design of COIL for industrial application is discussed. The scaled up COIL system of 1‐kW output power is now under trial operations. In these operations, a maximum output power of 1100 W, and a continuous operation time of more than 2 h with a power of over 500 W is recorded.
