Light-induced superconductivity in high-Tc cuprates

Pump-probe spectroscopy Initial attempts for controlling superconductivity were performed via photo-excitation [5 -7 ], microwave radiation 8 12 ,or photo-doping at optical frequencies [13, 14], achieving a T c enhancement of about one kelvin, increasing critical super-currents and energy gaps. Most of these experiments were

A 310 nm Optically Pumped AlGaN Vertical-Cavity Surface

At optical pump intensities ⪆2.0 MW/cm2, a narrow (<5 Å) laser mode at 363.5 nm emerges from the GaN luminescence. This mode becomes the dominant feature of the spectrum at higher pump powders, and addnl. modes appear ∼1.3 nm above and below this mode at 362.1 and 364.8 nm.

Developments and applications of THz polaritonics

The first was the semiconductor tin (II) sulfide, where optical pump terahertz probe spectroscopy was used to determine optimal conditions for sample growth to improve solar cell devices. These measurements revealed that by annealing and surface treatment, the carrier lifetime of tin sulfide can be extended, thereby improving device performance.

Tunable lasers at 1080 nm for helium optical pumping

We describe the current status of tunable, cw, solid‐state lasers in the infrared region of the spectrum which may be tuned to the helium resonance transition near 1083 nm. The principal use for these laser devices is the optical pumping of 3 He and 4 He atoms via the 2 3 S 1 metastable state. The tunable lasers we have examined include Nd 3+ ‐doped YAlO 3, La x Nd 1−x MgAl 11 O 19 (x

OSA | Radiative lifetime measurement of ultracold cesium

We demonstrate one simplified all-optical method to measure the radiative lifetime of ultracold cesium (Cs) Rydberg atoms. This method is based on photodetection of one ground state atomic absorption in a ladder-type electromagnetic induced transparency (EIT), which contains one ground state, one intermediate state, and one Rydberg state. In the presence and absence of optical pumping between
