我们研究了由连续锁模的Nd：YVO4皮秒激光泵浦的微微秒LiNbO_3偏振子激光器产生的窄带可调谐太赫兹。我们在非调谐模式下产生了高达5.4太赫兹的输出。我们使用腔内的标准具调谐了太赫兹输出，范围从0.51太赫兹到2.12太赫兹。在1.6THz太赫兹和0.9THz太赫兹频率下，分别获得了3.7THzW和2.4THz太赫兹输出功率。
We demonstrate narrowband tunable terahertz generation from a picosecond LiNbO3 polariton laser, pumped by a CW mode-locked Nd:YVO4 picosecond laser. We generated up to 5.4 μW of terahertz output in untuned mode. We tuned the terahertz output, using etalons in the cavity, from 0.51 to 2.12 THz. Terahertz output powers of 3.7 μW and 2.4 μW were achieved at terahertz frequencies of 1.6 THz and 0.9 THz, respectively.
