| Research Abstract |
We applied our beam shaping method to three kinds of laser diodes which have different lasing wavelength and different beam divergence angle. Elliptical beams emitted from the laser diodes were successfully transformed to nearly circular beams using a single substrate mirror. The dependence of the beam shape on the lasing characteristics was investigated numerically. Moreover beam quality factor of the tailored beam was observed and found to be as good as 1.24. We proposed an optical coupling system between a laser diode and an optical fiber based on the beam shaping method and estimated the coupling efficiency.
