A probe (usually made of noble metals such as gold or platinum) gently touches the electrodes of the laser chip. These probes are connected to the testing equipment to apply voltage to the chip. A forward voltage is applied to the laser chip through the probe, and the current passes through the active region of the chip (usually a double heterostructure composed of semiconductor material), exciting the recombination of electrons and holes, thereby generating photons. When the current reaches a certain threshold, the laser chip begins to emit laser light. At this time, the performance of the laser chip can be evaluated by detecting the emitted optical power. Once the laser is lit, a series of tests will be conducted, including the measurement of output power, wavelength, threshold current, operating voltage, and lifetime.
