Zusammenfassung:To enhance use efficiency of light in a pump utilizing absorption.SOLUTION: A pump 100 comprises: a porous body 10 that partitions a first space and a second space and has pores whose pore diameter is 10 times or less of the mean free path of internal gas; a selective absorption film 16 that is arranged so as to face the porous body 10 in the first space, and has a different reflectance for light depending on the wavelength; and a cooler 18 arranged in the second space, for cooling the porous body 10. The pump can heat the first surface of the porous body 10 contacting with the first space, to transfer gas from the second space to the first space through the pores.SELECTED DRAWING: Figure 1 【課題】吸収を利用したポンプにおいて、光の利用効率を高める。【解決手段】第１空間と第２空間とを仕切り、細孔径が内部の気体の平均自由行程の１０倍以下である気孔を有する多孔体１０と、第１空間において多孔体１０に対向するように配置され、波長によって光に対する反射率が異なる選択吸収膜１６と、第２空間に配置され、多孔体１０を冷却する冷却器１８と、を備え、第１空間に接する多孔体１０の第１面を加熱することによって、気孔を介して第２空間から第１空間へ気体を移送することが可能なポンプ１００とする。【選択図】図１
