We investigated the effective technique for debris suppression of a laser-produced tin plasma using a colloidal tin dioxide jet target, as well as the EUV emission and debris characteristics of the target. By using double pulse laser irradiation with an optimum delay of 100 ns, the EUV conversion efficiency of 1.2% at 13.5 nm was observed. The peak energy and intensity of ionic debris were simultaneously reduced by the double laser pulse irradiation. The peak kinetic energy of the singly-ionized tin ion was reduced from 9 to 3 keV, when an expanding low-density preplasma was produced. The dominant debris from a laser-produced tin plasma, which was deposited on a witness plate, was found to be oxidized tin (SnO ). By heating a witness plate at 100 °C, the deposited debris amount decreased to approximately one third. x

We have been developing high intensity vacuum ultraviolet (VUV) laser system for advanced applications such as micro and precise processing and photochemical reactions. We propose and construct a new VUV laser system to generate an output energy of sub mJ with a pulse width of subpicosecond at the wavelength of 126nm. A seed pulse was generated in Xe as the 7th harmonics of a 882 nm Ti:sapphire laser, and the Ar * amplifier media were generated in an optical-field-induced ionization Ar plasma produced by another 785 nm Ti:sapphire laser. The VUV radiation should be further amplified in a discharge-pumped Ar * amplifier, which is under construction. 2 2

Characteristics of emitted particles from a laser-produced tin plasma using a colloidal tin dioxide nano-particle jet target were investigated. By using double laser pulses, the EUV conversion efficiency at 13.5 nm and the ion energy were simultaneously regulated. Deposited amount of tin oxide was not well controlled, however. © CLEO Pacific Rim 2007.

We evaluated amplification characteristics of the nanosecond vacuum ultraviolet argon excimer emission at 126 nm, whose kinetics was initiated by high-intensity femtosecond laser-produced electrons. Subpicosecond 126 nm emissions were produced simultaneously as a result of the nonlinear wavelength conversion, which will be amplified in the amplifier. © CLEO Pacific Rim 2007.

We have developed a beam stabilization system for a high-power femtosecond laser operating at a repetition rate of 1 kHz. The beam position at a hollow fiber input was stabilized to within ± 1 um rms and the output fluctuation was significantly improved. © CLEO Pacific Rim 2007.
