Laser Applications Research Group (LARG)

1. Introduction

Laser Applications Research Group (LARG) is a research group funded by Ton Duc Thang University. Our general subject of interest is the application of laser based techniques in material processing and spectroscopy in particular ultrafast and terahertz spectroscopy. We investigate fabrication of nanomaterial by using laser ablation technique, optical properties of materials in THz regime by using THz time domain spectroscopy and nonlinear optical properties of material by using ultrafast optical Kerr effect and Z-scan techniques.

2. Mission and vision
