抄録

This paper reports a novel thermal lens microscope utilizing two laser pulses for excitation in order to enhance thermal lens signal via repetitive excitation-relaxation by the second pulse. The two-color excitation thermal lens microscope (TCE-TLM) system showed 80-times higher signal than a single-beam excitation TLM. By controlling duration between the two excitation pulses, TCE-TLM can measure non-radiative lifetime of photoexcited triplet state. The lifetime measurement can be applied to qualitative analysis, which cannot be realized in normal TLM.
