An analytical expression of depth resolution was derived through the beam parameter product and its angle of convergence with the assumption that the caustic surface of the focused beam has the shape of a single-cavity hyperboloid of revolution. For practical use of the derived relationship, formulas of the beam parameter product in resonators and lasers applied in practice are given.
Keywords: laser welding, laser cutting, focusing, laser beam, beam parameter product, depth resolution
