We produced 3–15 ns pulses at 10.6 μm wavelength to investigate efficient extreme ultraviolet and soft X-ray sources. A master oscillator power amplifier (MOPA) laser operating at a repetition rate of 10 Hz was built on transversely excited atmospheric (TEA) CO2 mediums. A scheme of a pulse-width tunable CO2 laser was proposed. The amplification by a 14-pass amplifier provided output energies of 150 and 60 mJ per pulse at durations of 15 ns and 3 ns, respectively. An initial observation of Gd plasmas produced by the CO2 laser shows that the spectral efficiency around 6.7 nm was improved by short laser pulses irradiation.
