Teaching content

Laser plasma diagnostics is one of important technic for fusion plasma.
For this diagnostics, a laser light source is the key component.
We are developing the ultra-high performance diagnostics to discover the frontier of the fusion plasma by developing the laser light source and related optics to achieve.
