Grumpy_Mike:
why can't it be mentioned in one or 2 sentences? Like this, "That won't work because X, Y, Z"
This won't work because a laser presents a varying impedance to the thing driving it and so a simple resistor will not be able to give it the constant current it needs.
ok, then I figure you would just use a transistor in between the laser driver and the laser diode. That way the driver always has power applied to it and the diode would just be rapidly swtched on/off. Would that work?
