Toward MW Tunable Coherent THz Parametric Source
Ming-Hsiung Wu, Cang-He Kuo, Jie-Ru Chen, Yen-Chieh Huang, National Tsing Hua University (Taiwan)
We have generated 0.2~0.3-MW peak power at 5.7 THz from a KTP difference-frequency generator. In my presentation, I will update the audience our most recent result toward generation of MW power from our unique source.

MW-class LED-pumped Solid-State Laser
Xuan-Long Ho, Ming-Hsiung Wu, Yen-Chieh Huang, National Tsing Hua University (Taiwan)
We report a high-power LED-pumped Nd:YAG laser. When operating at a quasi-CW mode, the laser produced 450-mJ energy at 1064 nm in a 550-μs pulse width. When operating at a Q-switched mode, the laser produced 278-mJ energy in an 80-ns pulse width, which has a corresponding peak power of ~3.5 MW.

Simultaneous Spectral Switching and Q-switching in a Dual-Wavelength Nd:YVO4 Laser Based on Electro-Optic Aperiodically Poled Lithium Niobate
Lin-Ming Deng, Chi-Meng Lu, Tien-Dat Pham, Hung-Pin Chung, Quan-Hsiang Tseng, Yen-Hung Chen, National Central University (Taiwan)
We demonstrate a dual-wavelength Nd:YVO4 laser where either or both of its emission lines can be simultaneously selected and Q-switched electro-optically (EO) using an intracavity domain-engineered LiNbO3, designed based on aperiodic optical superlattice technique. EO spectral and Q-switching at dual 1064- and 1342-nm lines, single 1064-nm line, single 1342-nm line, and their second-harmonic and sum-frequency generation lines has been achieved with this novel laser system simply by voltage control.

Passively Mode-locked Dark and Bright Pulsed Laser
Martin Brunzell, Max Widarsson, Fredik Laurell, Valdas Pasiskevicius, Applied Physics (Sweden)
A mode-locked source operating at 1064 nm producing 14 ps bright pulses and synchronously generating dark pulses with similar width at 1342 nm, with a repetition rate of 276 MHz and output power of 102 mW is demonstrated. It is achieved by two Nd:YVO4 cavities operating at different wavelengths that interact in shared section through a PPRKTP crystal phase-matching for sum-frequency mixing.
