采用纳秒级绿色激光脉冲和级联的非临界相位匹配LiB_3 O_5晶体（每个晶体长45 mm），实现了一个由光涡旋泵浦光参量振荡器构成的超宽带（>2倍频程）可调谐光涡旋激光器。利用该系统，在0.67-2.57 μ m的极宽波长范围内产生光涡旋输出。(C)2017日本应用物理学会
We demonstrate an ultra-broadband (>2-octave band) tunable optical vortex laser comprising an optical-vortex-pumped optical parametric oscillator by employing a nanosecond pulse (similar to 10 ns) green laser and cascaded non-critical phase-matching LiB3O5 crystals (45mm long each). With this system, an optical vortex output was produced over an extremely wide wavelength range of 0.67-2.57 mu m. (C) 2017 The Japan Society of Applied Physics
