Distortion of optical feedback signals in microchip Nd:YAG lasers subjected to external multi-beam interference feedback 下载免费PDF全文
This paper proposes a theoretical analysis for the
characteristics of an external cavity Nd:YAG laser with feedback of
multiple-beam interference, which is induced by the multi-reentrance
of the light from the external Fabry--Perot cavity. The theoretical
model considers the multiple beam interference of the external
Fabry--Perot cavity. It is found that the optical feedback signals
are distorted to pulse waveforms instead of the sinusoidal ones in
conventional feedback. The experimental results are in good
agreement with the theoretical analysis. The obtained theoretical
and experimental results can advance the development of a laser
feedback interferometer. 相似文献
