      Sir I want to ask about the CW laser used in the lidar sensor system given in optisystem 15. What type of CW Laser is used here? is this VCSEL or DFB or anyother laser??

      In which example do u mean?

      Sir I am working on the lidar sensor which is already given as an example in optisystem 15.I am looking for a different laser source which can behave in the similar fashion like CW laser and can be used in this application. Since CW laser is an externally modulated laser is there any other externally modulated laser which i can use in lidar application?

      Hi Manu,
      there are different kinds of laser sources that can be used, for example
      VCSEL, Directly Modulated Laser Measured, and Laser measured.

      in each of them, you can control the output optical power by modulating electrical signal.

      Hope that helps,
      thanks

      Thank you sir. But can you tell me what exactly is the CW laser given in the optisystem. Is it a FP laser or DFB laser or any other laser operating in the CW mode or it is entirely a different laser.

      Manu,
      each laser has a different model. CW laser outputs unmodulated CW laser based on the user input.
      with modulated laser has output modulated by the input electrical signal.
      I encourage you to have a look at the manual of each lase source!

      hope that is clear.

      thanks
      Mohamed
