Noncollinear broadband terahertz-pump-terahertz-probe spectroscopy of semiconductors
Optics InfoBase Conference Papers (2010)
Abstract:
Saturated absorption and intervalley scattering in n-type semiconductors were observed using noncollinear THz-pump-THz probe spectroscopy with ultrabroadband probe pulses. © OSA / UP 2010.Nonlinear josephson effect in High-Tc cuprates

Abstract:
The high-temperature superconductor La1.84Sr0.16CuO4 is excited with high intensity terahertz pulses tuned to the 1.9-terahertz Josephson Plasma Resonance. The strong interlayer tunneling current modulates the microscopic properties of the superconductor. © OSA / UP 2010.Single-shot detection and stabilization of carrier phase drifts of mid-IR pulses

Abstract:
We introduce a new scheme for single-shot characterization of the absolute-phase jitter of mid-IR pulses. The system detects phase drifts of self-phase stabilized sources; a control scheme compensating long-term drifts is also demonstrated. © OSA / UP 2010.Ultrafast resonant soft X-ray scattering in manganites: Direct measurement of time-dependent orbital order

Abstract:
We present ultrafast resonant soft-x-ray diffraction measurements of time-dependent orbital order in the single-layer-manganite La0.5Sr1.5MnO4. These experiments reveal the appearance of a metastable phase with reduced ordering, different from any thermal state of the system. © OSA / UP 2010.Noncollinear Broadband Terahertz-pump—Terahertz-probe spectroscopy of semiconductors
