In this talk I will discuss some of our recent work aimed at controlling superconductivity in the High Tc cuprates with light.
High-field THz and mid-infrared radiation are used to manipulate low frequency excitations in the superconducting and in the underdoped phases.
The first key result...

When femtosecond laser pulses are focused on nanometric metal tips, electrons are emitted. For few-cycle laser pulses, the liberated electronic matter wave can be driven back towards to parent tip when the laser field flips sign. At the tip's surface it can scatter elastically, gain more energy in the laser field, and travel towards...

We use high resolution time- and angle- resolved photoemission spectroscopy (tr-ARPES) to directly probe collective dynamics after optical excitation and study their influence on quasiparticles dynamics, Cooper pair formation, superconducting gap and...
