Pulsed lead vapor laser with high peak and average output powers

An average output power of 0.3 W was achieved at the wavelength of the λ = 0.7229 μ line of lead. This value was obtained for pulses of 2.5 kHz repetition frequency. The peak output power reached 34 kW, which was an order of magnitude higher than that achieved for the same laser in earlier investigations. The specific peak output power was 300 W/cm³.
