| Outline of Final Research Achievements |
A light source emitting ultrashort laser pulses at wavelengths ranging from deep ultraviolet (DUV) to vacuum ultraviolet (VUV) for a high-performance laser ionization mass spectrometer has been developed. A fundamental ultrashort laser pulses at a wavelength in the near-infrared region (800 nm) were converted into broadband DUV ultrashort pulses at wavelengths of 266 nm and 200 nm through a high-order harmonies generation and four-wave mixing process using a nobel gas as a nonlinear optical medium. In addition, we determined pressure conditions and beam focusing geometries to obtain the maximum conversion efficiency for DUV and VUV, and led to a way to improve the conversion efficiency. A 160-nm radiation was successfully detected by a simple spectroscopic measurement apparatus for VUV developed in this research.
