Question Audio Modulation on the M140 diode

Hi all.

Thanks for amazing forum.

I'm looking to audio (analog) modulate the M140 diode. I have done this with a cheap 5mw laser pointer. This was possible because the drivers output is proportional to the input. So I used a basic transistor circuit and audio from a 3mm jack.

Now with a more powerfull diode like the M140 I will need a 2A driver with analog modulation capabilities. So I found the FlexMod P3. But they are rare, there is group buy running at the moment.

This is my first group buy so I'm not sure how long it may take, and I need them very urgently.

So my questions are:
1. Is there anyone willing to sell me 2 FlexMods as soon as possible?
2. What are my alternative options to the FlexMod?
3. I build a basic constant current driver quite easily before, but can't find any circuit diagrams on a analog driver. Will this be very complex built?

Thanks for great forum

Regards
