<p>A method an apparatus for manufacturing a microfluidic device (10) is disclosed in which a laser is used to remove selected portions of one of the layers that make up the device. The portion of the layer may be removed before the layer is amalgamated with other layers making up the device, or the portion may be removed after the layers have been bonded together. The laser beam used to accomplish removal is a combination of at least two laser beams (3, 4), one of which (3) may be a continuous beam to form a melt of the portion to be removed, the other (4) being pulsed or modulated in some way to periodically induce shockwaves which remove the portion. The laser beams use at least one part (5, 8, 9) of the same alignment system.</p> |
