Ultrafast Optical Properties Lab
Machine-translated · View original
A lab that explores the ultrafast behavior of crystals with ultrashort pulse lasers.
AboutAbout the lab
Exploring ultrafast optical properties with ultrashort pulse lasers.
The lab uses ultrashort pulse lasers of about 10 femtoseconds (1 femtosecond is one quadrillionth of a second) to conduct basic and applied research on ultrafast optical properties of matter.
In crystals such as two-dimensional layered materials, it generates lattice vibrations with aligned phase (coherent phonons) and attempts to control phase transitions.
The lab also pioneers nonlinear photonics in diamond, aiming for applications such as optical circuits.
Key terms
- Ultrashort pulse laser
- A laser that emits light for only an extremely short time, on the order of 10 femtoseconds
- Coherent phonon
- A lattice vibration with aligned phase in a crystal, excited by an ultrashort pulse laser
- Phase transition
- A change of the state or structure of a material into another state or structure
