About us

The Kurihara Laboratory is a newly established research group launched in April 2025. Our laboratory conducts experimental research in the field of optical properties, which investigates the characteristics of matter using light. By employing powerful laser pulses that last only 10^–15 seconds (femtoseconds) as a kind of “stroboscopic shutter,” we can visualize, in the time domain, the dynamics of elementary excitations in solids such as magnons, phonons, excitons, and plasmons. Making full use of these laser and light-source technologies, we aim to develop original measurement methods and carry out experiments in solid-state physics that cannot be realized elsewhere.

The topics we are currently most interested in include:

• Observation of “ultrafast fluctuations” of elementary excitations through statistical analysis of femtosecond laser “noise”
• “Sub-cycle quantum optics” in the terahertz regime
• Development of ultrashort-pulse lasers for nonlinear spectroscopy of solids

…and more!
