Laser Diode Driver For precision pulse shaping
Laser diode driver to generate any pulse shape with nanosecond pulse duration. It is a multifunctional unit with integrated AWG (Arbitrary Waveform Generator), TEC controller & multiple pulse delay generators for signal synchronization. 2 models for either direct (laser diode) or external (EOM or AOM) pulse modulation. (Note : EOM=Electro optic Modulator ; AOM = Acousto-Optic modulator)
Key features :
• Direct modulation of ns laser pulses with any shape
• 0 to 1.6 A output current with 16 bit/48 dB/30 μA resolution
• Integrated pre-configured mounting sockets for type 1 butterfly laser diode (type 2 on request)
• User set pulse shape from 500 ps to 8 μs with 0 - 20 MHz repetition rate
• Integrated TEC controller with over temperature protection
• Special mode for laser diode “gain switch peak” suppression
• Built-in pulse AWG with internal or remote triggering
• 3 integrated Pulse Delay Generators
• USB interface with intuitive GUI software
• Available in two versions direct or external modulations
