Microcollimated laser diode with low wavefront aberration
Abstract
The authors developed microcollimated laser diode( MCLD) utilizing a 1 mm short focal length, phi, lc 0.5 mm small diameter micro Fresnel lens (MFL) for the first time as the collimating lens. The MCLD is assembled with a 780 nm quantum-well laser diode dice and an MFL in the smallest commercial available laser package. The radiated laser beam form the MCLD has higher than 2mW power at 50 mA driving current, narrow enough as a phi 2 mm beam diameter with nearly Gaussian intensity profile, and low wavefront aberration less than {lambda}14 (rms value) measured at 1 m distance.
