Product Description

Technical Advantages

1. The internal design uses high-voltage pumps and narrow pulse switch drive technology to power the pulse diode. This technology reduces the speed impact caused by the LD's parasitic inductance, enabling a pulse constant current source with rise and fall times less than 15ns and a pulse amplitude greater than 30A, resulting in excellent narrow laser pulses.
2. The internal pulse constant current source can adjust the laser source pulse width via a pulse train network, ensuring stable waveforms and good shape.

LD and Output Pin Connection
As shown in the figure, the positive terminal of the pin should be connected to the gold wire side of the LD laser tube, and the negative terminal should be connected to the other side. To ensure a good laser current pulse shape, do not extend the wires arbitrarily.
Note: When connecting, make sure to unplug the power supply before soldering to prevent static damage to the LD. During use, be cautious as the LD output pin should not touch any other cables, interfaces, or metal surfaces, as this may damage both the LD and the power supply. This port may have up to 100V DC, so safety precautions are necessary.
