Abstract

A supercompact microcollimated laser diode (MCLD) was developed without attaching any other external collimating lens. The MCLD consists of 780-nm quantum well laser diode dice and a microcollimating lens in the smallest commercially available laser package. In addition, the MCLD has high reliability against humidity and temperature variations, as all of the elements are assembled in the package filled with dry nitrogen gas. A short focal length micro Fresnel lens is used as the collimating lens to obtain the compact MCLD and narrow collimated laser beam. Additional details are provided on the micro Fresnel lens, the quantum well laser diode dice, and the microcollimated laser diode.
