Abstract

A lamp-pumped laser includes a pump light source for optically pumping a laser medium, such as a laser rod, a pump light sensor that detects the optical pumping power of the pump light source, and a control unit connected to receive an output signal from the pump light sensor and to increase the electric power of the pump light source on the basis of the detected optical pumping power and in correspondence with a predetermined rise characteristic of the optical pumping power.
