Using third-harmonic microscopy to measure ultrafast phase transition in vanadium dioxide Conference Paper uri icon

abstract

  • The measurement of ultrafast phase transition in vanadium dioxide was investigated using third-harmonic microscopy. A long cavity Cr 4+:forsterite femtosecond oscillator generating pulses ∼50 fs in duration with the output energy >10 nJ, was used for the investigation. The density dependence of the third harmonic amplitude as a function of the intensity of the incident radiation was measured. the temperature-dependent measurements show evidence of hysteresis behavior of the phase transformation on a microscopic scale.
