作者：M Gilewski 摘要：The article describes a digitally controlled laser diode driver. This driver includes: power supply circuit, measuring circuit and FPGA controller. A laser diode current is produced by the power supply circuit. The level of this current is controlled by FPGA. A monitoring photodiode current is measured by the measuring circuit. The photocurrent level is recorded by FPGA. Its value determines the amplitude of laser current. The controller can operate with laser diode currents up to 1A. A driver frequency band is less than 10kHz. |
