hi

just wonder if LED can be used in place of laser diode in simulating the pulsed laser driver circuit in LT spice

thank you
 

There are some interesting aspects to laser diodes, which may
not have an electrical signature in SPICEs - for example there is
a threshold current below which you get light but not coherent,
and you want to stay on the right side of. And there is variation
of wavelength with temperature & power, etc. which might drive
you (heh) to control "on" current carefully as well.
