The TL@NTU Advanced Laser Technology team aims to lead the frontier research in laser technology. There are three main areas of research for this centre:
- Fibre Beam Combiner
- High Power Fibre
- High Power Laser Diode
Fiber Beam Combiner
Led by Dr Lai Wennjing
Our research works mainly focus on the design and development of high-power fibre laser systems and fibre optic components operating at the near and mid IR regimes to meet the challenges of next generation defence applications.
We have successfully delivered high power Ytterbium and Thulium doped fiber laser with excellent beam quality, good slope efficiency operating at around 1 µm and 2 µm of wavelength. In addition, we also fabricate low loss fiber beam combiners for high power operations.
High Power Fibre Team
Led by Prof Yoo Seongwoo
A cutting-edge fibre technology has opened a new pathway to the frontier of fibre optics and photonics. With the state-of-the-art fibre drawing facility, we have been leading the development of specialty fibres for fibre lasers and devices in various applications spanning from direct energy to quantum photonics.
We have In-house capability to design and fabricate spatial mode control fibre for extremely high-powered laser beyond the ultimate self-focusing limit, and specialty fibre for transverse mode suppression in high power ultrafast fibre laser applications.
High Power Laser Diode
Led by Dr Liu Chong Yang
In TL@NTU, our research works in this field mainly focus on the design, fabrication and characterization of high power semiconductor lasers ~ 980 nm wavelength range.
We have successfully developed the whole fabrication process of high power laser diode in Tl@NTU, including facet coating, chip on submount bonding. And we have fabricated high power laser diode based on laser bar technology as well as based on single emitter technology.
