| 英文摘要 | The relationship between the photothermal cooling efficiency of a micro-cantilever's mechanical mode and the environmental temperature is studied. The micro-cantilever and a polished fiber end form a low finesse Fabry-Perot (FP) cavity. Experimental results in a temperature range from 77 K to 298 K show that temperature has an obvious influence on photothermal cooling efficiency. The photothermal cooling efficiency, eta(ph), at 100 K is 10 times that at 298 K. This accords well with the theoretical analysis that the high photothermal cooling efficiency can be achieved when photothermal response time, tau(ph), and mechanical resonant frequency, omega(0), are close to the optimal photothermal cooling condition omega(0)tau(ph) = 1. Our study provides an important approach for high effective photothermal cooling and high-sensitivity measurement for force microscopy. |
