Overview

uniLDD is a DC input power converter designed to supply CW or pulsed (QCW) current for the single emitter, bar, stacked laser diode or high power VCSEL in constant current mode. Using different software versions together with specific hardware sets, the uniLDD driver is adapted for different types of laser diodes and modes of operation. The driver is based on DSP technology assuring high specifications. Typical performance is presented in below illustrations. Next optimizations are done while adapting according to customer requirements (current, voltage, cables…):

• Firmware version (chosen from different 5 ready versions)
• Hardware components set
• Regulation loop frequency response analysis and PID constants defining
• Hardware and software settings

One or two TEC control channels can be added as option. However, the price for the feature is reduction of maximal possible output current to laser diode since 2 or 3 output stages of total 5 are utilized for TEC supply.

Features

  • Best suitable for high-current and high-power applications
  • Different firmware versions featuring CW, QCW, TEC control operation
  • Hardware versions for CW, QCW, TEC control, Conductive cooling options
  • At factory frequency response analysis is used to optimize performance to achieve stable operation with particular laser diode and connection cables combination
  • High efficiency switching mode converter
  • Multi-phase power stage for low current ripple
  • Low current drift
  • Parallel operation of two drivers to double output current
  • “Voltage booster” layout option to extend output voltage to 200V and more
  • External storage capacitor option for long-pulse QCW operation
  • Analog and digital (CAN, RS232) control interfaces
