Tunable terahertz generation in the picosecond regime from the stimulated polariton scattering in a LiNbO crystal.

We demonstrate narrowband tunable terahertz generation from a picosecond LiNbO polariton laser, pumped by a CW mode-locked Nd:YVO picosecond laser. We generated up to 5.4 μW of terahertz output in untuned mode.

Multiwavelength ultrafast LiNbO(3) Raman laser.

We present a multiwavelength ultrafast Raman laser based on lithium niobate which uses polariton scattering in combination with Raman scattering to selectively generate new wavelengths from a nanojoule-scale picosecond pump laser. Pumped by a 1064 nm pump laser, the system generates 1123 nm by stimulated polariton scattering (SPS) and 1140 nm by stimulated Raman scattering (SRS). Cascading of these intracavity fields generates 1155 nm and 1174 nm, as well as generating THz output.

Highly efficient picosecond diamond Raman laser at 1240 and 1485 nm.

We present a highly efficient picosecond diamond Raman laser synchronously-pumped by a 4.8 W mode-locked laser at 1064 nm. A ring cavity was adopted for efficient operation.
