Detailed Description | LDD-1121 | Laser Diode Driver
The LDD-1121 is a specialized Laser diode driver able to work as CW Laser diode driver or Laser diode pulse driver. Core element of the LDD's internal current source is the generation of highly precise 333 ps timing steps that results in 1 mA resolution and very low ripple. Typical applications for the LDD-1121 are second harmonic generation (SHG), third harmonic generation (THG), and ultrashort pulse Laser.
Equipped with optional light measurement circuitry, the LDD-1121-SV-LPC can also be operated as a Laser Power Controller (LPC).
All LDD-1121s offer various safety features, including an input for Laser diode temperature monitoring. They are fully digitally controlled; their firmware is upgradeable to offer various communication options and to meet specific customer requirements.
