Lasers Last Revised: 2023-02-08

Laser is one of the most important and essential light sources for various researches and applications. Laser research in DOP includes laser physics, laser engineering and laser applications. Laser physics research focuses on the fundamental study of laser behaviors, materials, dynamics, non-linear optics, and ultra-fast phenomena. Laser engineering research is on developing various laser systems, components, schemes and operation conditions. Laser applications research covers a broad range of different research topics and fields using lasers with various wavelengths, pulse durations, energy levels and spatial behaviors. The laser research group closely works with other researcher and research groups by supporting and establishing different laser system to meet their research requirement. The expertise of Prof. Y. H. Chen in on nonlinear optics and designing/manufacturing lithium niobate-based laser systems and laser devices. Prof. C. Y. Tai devotes in ultra-fast laser system and time-resolved non-linear spectroscopy. Prof. T. Y. Chung works on volume Bragg grating which serves as the laser component to control laser mode behavior and wavelength. In the meantime, photoacoustic, photoluminescence, and lock-in thermography are developing for inspecting various specimen. Prof. J. F. Chang works on electrically-pumped organic laser and high efficiency organic optical devices. The expertise of Porf. K. T. Cheng in on liquid crystal which can serve as laser host material for laser operation with the advantage of electrical control and optical characteristic of liquid crystal.
