parallel with the LED. Therefore the current can only flow through the LED for a short while until the all the current available is shunted through the inductor instead.
That's a pretty big inductor. Why would you burn power unnecessarily?
In case this has not already been cited, I have successfully used the following circuit as the laser driver in a distance measuring application

Thanks for your reply. I saw it but the idea seemed a bit obscure for my to spend time on. My limitation, not yours.
I'll have a look at your sim below, but it may take me a couple days...
Thanks for the consideration!
