Just joined and having fun going through the various threads, been reading page after page after thread, and jumping off to Google / Wikipedia looking up all the terms and soaking up all the knowledge I can glean by lurking.
I like learning new stuff.
One thing I'd like to ask is are there any EU members who sell green lasers? 150mW or so will be fine, not looking to set the cat on fire here. I've already bitten the bullet and ordered a blue + goggles + bats/charger.
Also has anyone shone a laser into a geode? I would have though if you have a really nice clean geode, the reflections from the crystals inside it, and the shape causing the light to bounce from side to side before exiting, should produce rather spectacular effects, even more so if you shine a few colours in at once.
For now I'm enjoying playing with reflecting off different surfaces (45 deg angle, natch), and seeing the different diffraction patterns they produce - even the so called highly polished metals.
And I've also got a glass topped coffee table which is great for actually seeing the green beam bounce internally for a good 10 ~ 20cm inside the glass
