Experiments

1. Measure the far-field distribution of the beam and calculate its vertical and horizontal divergent angles.

2. Measure the voltage-current characteristics.

3. Measure the relationship between output optical power and current, and acquire its threshold current.

4. Measure the relationship between the output of optical power and current at different temperatures, and analyze its temperature characteristics.

5. Measure the polarization characteristics of the output light beam and calculate its polarization ratio.

6. Optional experiment: verify Malus’s law.
