High-field long-wavelength infrared pulses are important for the emerging fields of laser-driven proton acceleration and laboratory astrophysics. We present experiments on generating intense single-cycle long-wavelength infrared pulses by using self-phase modulation in laser-plasm interaction as well as our plan of constructing high-field CO2 laser from 1-TW to 100-TW.

 

We report tunable narrow-line kW-class far-infrared laser radiation between 1.8-6
THz from off-axis parametric oscillators using lithium niobate and KTP as gain crystals.
These high-power sources open up high-field applications such as THz nonlinear optics and
particle acceleration.

 

Polarization engineering and characterization over a wide spectral range are
essential to investigate the symmetry properties in matter and to control light-matter
interactions. ATTO-EUV laboratory in NTHU for the first time demonstrates that highharmonic ellipsometry, using the polarization degree of freedom, is able to unveil the quantum
nature of the high-order nonlinear dipole response.

 

We report the study of leading-edge integrated quantum photonic technologies for
realizing scalable photonic quantum chips with the ability to perform fault-tolerant quantum
computation at room temperature. Two qubits CNOT gate for measurement-based computing
has been demonstrated with a highly integrated entangled quantum optical source.


 

We have measured the intensity noise of a cascaded mode-locked Nd:GdVO4 laser. Adopting 10 mm long KTP crystal and type II nonphase-matched SHG process, the 1.6 – 300 kHz rms intensity fluctuations are reduced from 0.368 to 0.035 by a spectrally controlled VBG.

 

A plasmonic cavity with extreme small mode volume provides a platform for quantum strong coupling to an emitter at room temperature. However, to precisely position an emitter into the cavity is challenging. In this work, we use oligonucleotide (short DNA) to integrate the fluorophores into the plasmonic cavity.
