PURPOSE:To set the amplification efficiency of an amplifier best, and increase transmission efficiency. CONSTITUTION:A laser oscillator 1, a first stage amplifier 2a, a middle stage amplifier 2b and a final stage amplifier 2c are arranged. Beam split mirrors 5a are arranged between the respective amlifiers 2a, 2b, 2c. A second split mirror 5b, a total reflection mirror 6, and a converging lens 7 are arranged on the downstream side of the first beam split mirror 5a. The laser light from the converging lens 7 is transmitted to a dye laser 9 via an optival fiber 8. |
