Title:
LASER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/184243
Kind Code:
A1
Abstract:
A laser device, comprising a substrate (11), and a seed laser and a radio frequency coil (12) that are disposed on the substrate, two ends of the radio frequency coil being connected to corresponding pin terminals of the seed laser respectively. The seed laser and the radio frequency coil are disposed on the substrate by means of designing the laser device, and the two ends of the radio frequency coil are connected to corresponding pin terminals of the seed laser respectively, aiming at achieving low inductance and reducing a voltage drop caused by a high-current pulse; and reducing the electrical induction thereof, thereby reducing reflection and preventing standing waves between the seed laser and a pulse current driver; and by means of a resistor-capacitor (RC) snubber circuit, obtaining a flat-top current pulse that passes through the laser.
