This new laboratory is lead jointly by Dr. Jyhpyng Wang and
Dr. Szu-yuan Chen, and collaborators Dr. Chau-Hwang Lee from
Institute of Applied Sciences and Engineering, Academia
Sinica, and Prof. Jiunn-Yuan Lin from National Chung-Cheng
University. Current emphasis of research is in the development
of advanced optical techniques and applications of ultrafast
technology in high-field physics.
In ultrafast laser technology, the Laboratory continues
developing femtosecond pulse amplifiers, studying how to
correct spatial and temporal phase aberration and how to
compensate nonlinear effects, for the purposes of increasing
energy gain and pulse contrast. In the mean time the
Laboratory also develops spatial-temporal ultrafast waveform
measurement techniques, to study nonlinear pulse propagation
and to monitor online the waveforms of high power pulses in
real time.
In optical technology, the Laboratory continues developing
differential confocal microscopy, a far-field technique with
nanometer depth resolution. Spatial encoding/decoding methods
are studied for breaking the diffraction limit in all three
dimensions. Combined with laser based optical pressure as a
driving force, this advanced technique is used to measure the
viscoelastic properties of living cells and biomembranes. It
is also a convenient tool for rapid online inspection of
semiconductor surfaces and optical disks.
In high-field physics, the Laboratory has recently started
experimental research in femtosecond high-power laser excited
x-ray laser. Such x-ray lasers have the characteristics of
ultrashort pulse and high peak power, suitable for the
development of time-resolved spectroscopy and plasma based
nonlinear optics in the x-ray region. They can also be used in
cellular microscopic tomography and nanometer lithography.
Experiments on tera-watt femtosecond laser induced plasma-wave
electron accelerator are also under construction. Such
accelerators have extremely large acceleration gradient,
representing the newest approach in accelerator technology.
Other related new frontiers, such as laser induced nuclear
reactions, laser induced K-shell x-ray emission, light
scattering by relativistic electrons, are also directions for
exploration.
