Abstract

The present invention provides a nanoparticle manufacturing system differing from conventional nanoparticle fabricating equipment. In this nanoparticle manufacturing system, a laser beam emitted from a laser source is directly guided to the surface of a target disposed in an ablation chamber through a light guide tube, such that the laser beam is prevented from being influenced by reflection and/or refraction effects occurring from the cooling liquid filled in the ablation chamber. Moreover, in this nanoparticle manufacturing system, a light guidance-out end of the light guide tube is controlled to be apart from the target surface by a specific distance (<5 mm). Thus, the laser beam is able to effectively process the target to a plurality of nanoparticles by way of laser ablation, in spite of the laser beam provided by the laser source is a low-power laser beam (<30 mJ/pulse).

Dependent claims

A nanoparticle manufacturing system, comprising:

an ablation chamber, having a transparent window on the top thereof;
a substrate, being disposed in the ablation chamber for a target being put thereon;
a cooling liquid inputting device, being connected to the ablation chamber via a cooling liquid transmitting tube, and used for inputting a cooling liquid to the ablation chamber;
wherein a liquid surface height of the cooling liquid is controlled to be apart from a disposing height of the transparent window by a first distance, moreover, the liquid surface height being apart from the surface of the target with a second distance;
a laser source for providing a laser beam;
at least one light guide tube, having a light guidance-in end connected to the laser source and a light guidance-out end, wherein the light guidance-out end is extended into the ablation chamber for being apart from the surface of the target with a third distance;
wherein the laser beam emitted by the laser source is guided into the ablation chamber through the at least one light guide tube, so as to process the target to a plurality of nanoparticles.
