Semiconductor Laser Physics Lab Experimental Instrument
Product Overview
The experimental device measures semiconductor laser power, voltage, and current to help users understand the continuous output characteristics of semiconductor lasers. The fluorescence emitted when the injection current is below the threshold and the spectral line variations when laser oscillation exceeds the threshold can be observed using an optical multichannel analyzer.
Applications
- Measurement of semiconductor laser power, voltage, and current
- Study of continuous output characteristics of semiconductor lasers
- Observation of fluorescence emission below threshold current
- Observation of spectral line changes above threshold current
- Spectral analysis using an optical multichannel analyzer
