摘要：

Photocoloration of microcrystalline powder of a spirooxazine compound by femtosecond laser pulse excitation, depending on its intensity, is reported with transient absorption spectral measurements of the powder. The mechanism is discussed in terms of light induced local heating and succeeding cooling of a small volume in the microcrystal.
