Abstract
A microcollimated laser diode (MCLD) utilizing a 1-mm short focal length, phi 0.5-mm small diameter micro Fresnel lens (MFL) as the collimating lens is discussed. The MCLD is assembled with a 780-nm quantum-well laser diode dice and an MFL in the smallest commercially available laser package. The radiated laser beam from the MCLD has a power of higher than 2 mW at 50 mA driving current, a phi 2 mm beam diameter with a nearly Gaussian intensity profile, and a low wavefront aberration of less than lambda /14 (RMS value) measured at a 1-m distance.<>Keywords
