Abstract

Ultrabroadband nanosecond red-IR oscillation of up to 370 nm from longitudinally pumped Ti³⁺-sapphire laser has been achieved. The 'spatially-dispersive' laser resonator employed a prism pair, an intracavity cylindrical lens, and a diaphragm allowed to maintain the lasing conditions simultaneously for different spectral components in different areas of acting element. Second harmonic radiation from a Q-switched YAG:Nd³⁺ laser with 532 nm oscillation wavelength and 200 mJ pulse energy was used as a pumping source. Stable giant pulse operation of ultrabroadband Ti³⁺ sapphire laser in 680-1050 nm range with pulse energy of up to 30 mJ, pulse repetition rate of up to 10 Hz and 15 percent pumping to lasing efficiency have been obtained.
