Abstract

An experimental method is proposed to increase the output power from a C-aperture very-small-aperture laser (VSAL). This method is based on the resonant property of a C aperture and the tunability of the emitting wavelength from a VSAL. The drive current of the VSAL is altered to tune the emitting wavelength. The experimental results indicate that, when the emitting wavelength matches the resonant wavelength of the C aperture fabricated on the VSAL, the output power is enhanced 7.2 times. So a strong output power from a C-aperture VSAL can be obtained with small power consumption. This study may be useful to the design and application of a VSAL.
