Abstract :
We have investigated the terahertz (THz) emission from lithium ternary chalcopyrite crystals illuminated by 1560-nm femtosecond pump laser pulses. Monocyclic THz emission and narrowband THz emission from the coherent phonons in LiInSe2 and LiGaSe2 were observed at 2.87 and 3.45 THz, respectively.
