Laser components

Laser driver with or without modulation

Laser Driver 1290 series is used for driving laser diodes with an output power of up to 40mW and an operating current of max 100mA. All drivers has APC automatic power regulation of the laser diode as back connection from monitor diode, slow start of the laser diode at voltage setting, protection against ESD for the laser diode and protection against reverse voltage polarity.

Characteristics
Laser driver
  • Input voltage from 3 to 6V
  • Automatic power regulation (APC) of the laser power
  • Good laser power stability at temperature variations
  • Laser diode shuts down at too low current or too high temperature
  • The analogue modulation frequency is 0-100kHz (sinus)
  • The analogue modulation input is DC-connected and the modulation voltage is 0 to +1.3V, where 0V gives maximal output power and +1.3V gives zero output power.
  • Easy adjustment with a potentiometer
  • Dimensions: 64x12.2x9.5mm
