I've thought about that before, actually I think I might be able to dig up a .brd of it on my old laptop from like 2 years ago. I'm pretty sure there is a data sheet (I dont think its was lm3410 specifically, but same idea) that has a mosfet in one of the designs to extend the range and I basically modeled after that. I'll try to find it.
Anyways, two things in your design there I think need to be changed for it to work.
1. Move the pull up resistor to the Vin (before the coil) so crazy spikes and ripple aren't running into the gate of the fet.
2. Change it to a 100 ohm. Because of how fast the device switches I'm 99% sure the 1M resistor won't let enough current through to saturate the gate quickly, resulting in it operating in the linear region (where it has not high, but not its lowest resistance either) majority of the time. Basically it will be trying to pass large amounts of current while it is very slowly (relative to the operating frequency at least) moving to its minimum resistance and when it's somewhere around order of 1ohm it will be burning so much power the thing will worst case pop, best case be wildly inefficient and low output. A 100 ohm resistor should be low enough to let it open quickly and efficiently while still only leaking like 40ma when it's connected to ground by the internal fet.
Also @ nelly little late, but yeah you can make a nice and cheap laser if you pop an m140 and a mini drive set to like 1.25A in c6. You'll get long runtimes, reliable, and enough power to wow all your friends. Just make sure you get some laser safety glasses.
