What is that?
Direct drive 100+ mW laser from a DVD-RW drive?
Anyone try to transplant a diode from a quality keychain style pointer? Granted you would need a better battery solution than LR44's but those Li Ions used in Orb Raw's would probably work. 200+ mW at 650 nM anyone? Get a decent multi element collimator on there - it will enlarge the beam and make it circular. The penalty is about 20-50 mW but the divergence will be well under 1/2 mrad and it will go on forever. The collimators are about 10 mm long.
