For safety reasons Kinect probably don't use a 60mW IR laser. This would be a class 3 laser product which can be very dangerous. Moreover there is not warning laser label on Kinect, which is mandatory even for class 1 products. I suppose they use an high power IR LED that illuminates a matrix of microlenses representing the structured dot pattern with a secondary lens that projects the image of the focused dot matrix (as described in the US20100118123 patent from Prime Sense LTD http://www.primesense.com/ which is the company that conceived Kinect).
