This high speed laser diode driver can generate any programmable pulse shape with down to 500 picosecond and 48 dB dynamic range. It includes many functionalities like gain switch peak suppression and 3 synchronized pulse delay generators.

This high speed driver with integrated TEC controller delivers precision pulses which are generated internally by an on-board AWG (Arbitrary Waveform Generator). It is compatible with most of the laser diode form factors (Butterfly, TO etc.). Direct laser diode modulation is an alternative to EOM or AOM external modulation. See our fiber modulator basics tutorial for more information.

High speed laser diode driver KEY FEATURES :

high speed driver pulse shape
Example of a laser diode seeder pulse shape in a MOPA fiber laser configuration
  • Direct modulation of nanosecond laser pulses with any shape
  • Built-in pulse AWG with internal or remote triggering
  • 0 to 1.6 A output current with 16 bit/48 dB/30 μA resolution
  • Integrated TEC controller with over temperature protection
  • Special mode for laser diode “gain switch peak” suppression
  • Two versions for either direct modulation or external modulation (see spec table and pictures)
  • 3 Integrated Pulse Delay Generators
  • GUI software and several libraries software integration (LabVIEW, DLLs, Hexa, Python)


The GUI software lets the user have total control of all module functions. It includes several libraries for software integration ((Labview VIs, DLLs, Hexa, Python etc.)

Applications of this driver includes high energy laser seeding, LIDAR testing, etc.

This high speed laser diode driver  works alone or in series with other products in our range like :

high speed laser diode driver gains switch peak suppression
A gain switch peak suppression function is integrated


DFB or Bragg-based laser diodes such as Thorlabs, lumentum or 3SP are perfectly well controlled.

All Aerodiode products can be connected together with a single GUI interface which consolidates all module functions. This allows the users to save a lot of time.
