-Instrument Introduction

By measuring the power, voltage, and current of semiconductor lasers, students can understand the working characteristics of semiconductor lasers under continuous output. Observing with WGD-6 optical multi-channel analyzer, the fluorescence emitted by the semiconductor laser when the injected current is less than the threshold, and the spectral line changes caused by laser oscillation when the injected current is greater than the threshold.

-Product Features
