Title: Laser beam converging device
Inventor: MIYAZAKI HIROYUKI
IPC: G02B26/02
Filed: 1993-07-31
Abstract: PURPOSE:To set a beam diameter in the vicinity of a focusing position to a desired value by utilizing the aberration of a lens. CONSTITUTION:In a laser beam converging device, a case that the beam diameter 12 of incident light 10 is larger than the radius 14 of a lens L1, that is the lens diameter is equivalent to the aperture diameter is explained. The incident light beam 10 is converted into a converged light beam 16 when the incident beam is transmitted through the lens L1, the converged beam 16 is constricted on the optical axis 8 in the vicinity of a focusing position F1 and thereafter diverged. In general, since the laser beam transmitted through the periphery of the lens L1 is strongly affected by the influence of spherical aberration, a desired beam diameter 18 is obtained by positively utilizing it. Thus, the beam diameter 18 in the vicinity of a focusing position F1 is set by utilizing the spherical aberration of the lens L1. Namely, by making the aberration large and using it as a designing parameter, e.g. the characteristic having the large depth or focus around which the beam diameter rises sharply is obtained. Consequently, when the device is used for a bar cord reader, etc., it is useful for making the reading depth large.

Abstract: PROBLEM TO BE SOLVED: To prevent misfit transition by composing an n-layer of a specific semiconductor added with donor impurities for substantially equalizing the lattice constant with that of an emission layer while composing a p-layer of a specific semiconductor added with acceptor impurities having a band gap larger enough to confine the injected electrons in the emission layer. SOLUTION: A butter layer 2 of AlN is formed on a sapphire substrate 1 and then a silicon doped N<+> layer 3 having high carrier concentration of GaN, a silicon doped n-layer 4 of GaN, an emission layer 5 of In0.07 Ga0.93 N, a magnesium doped p-layer 61 of Al0.08 Ga0.92 N, and a magnesium doped contact layer 62 of GaN are formed sequentially thereon.

Furthermore, misfit transition of emission layer 5 incident to the misfit lattice between the n-layer 4 and emission layer 5 can be prevented because misfit of lattice is insignificant between the GaN and the In0.07 Ga0.93 N.
