Abstract

A signal LD 36 is driven by a signal LD driver 38 in response to a trigger signal, on which image data are superposed, and emits a pulse laser signal beam modulated by the image data. A pre-amplifier 42 and a power amplifier 46 include optical fibers, which are obtained by doping part of quartz optical fibers with an element such as erbium. Laser excitation beams emitted from excitation LDs are made to pass through and excite the optical fibers. The laser signal beam emitted from the signal LD 36 then passes through the excited optical fibers. This liberates the enhanced energy state and amplifies the intensity of the emitted laser signal beam. A clock generator 30 generates the trigger signal of a fixed period, in response to a control signal output from a control circuit 32. A superposition circuit 28 superposes the image data upon the trigger signal and outputs the resulting superposed signal to the signal LD driver 38. The structure of the present invention realizes highly efficient image recording without using any acousto-optic modulator (AOM) or similar element, and enhances the peak intensity when a thermally sensitive material is irradiated with the laser beam.
