Optical beam expander with a function of laser power detection |
摘要 |
An optical beam expander with a function of laser ray power detection provides an electric signal for feedback controlling laser ray power. By testing the power stability within a temperature range of 15 to 25° C., this apparatus demonstrates that it can stabilize an unstable laser to stable range of 5% when combined with a traditional self-controlling circuit arrangement.
