Abstract

A portable laser device for obtaining blood samples through the skin of humans or animals. A laser crystal is optically pumped to produce a short high power laser pulse which vaporizes a small hole in the skin. The pulse is shaped to produce a pulse cross section at a sampling location which has a long dimension and a short dimension similar to a blade cut.
