Hi, I'd like to ask, if its possible to shape a fire. Would it be possible on tealight ? I don't want complex shapes just simple ones like sphere, cylinder... Thanks

Ok you convinced me, I'll go with laser diode. YAG may be next one :O

@plantis : maybe you're right that 1W laser is quite tough for the beginning. But I think my electronical skills are good enough(I've done several projects so far) so I was only curious about the optics part(maybe i'll buy book). To the safety, I was alredy familiar with the article you posted...

@platis: I've been just googling for several hours but I still don't understand what you meant. I see you have masters at laser science, but I am just high school student. Can you please explain me in little more detail ? Where can I get so cheap YAG laser? What is that YAG glass atc... I still...

well those 5mw would cost much more than one 1w(and i am not speaking about synchronization...) That Nd:YAG looks interesting, but I hardly think that I can find 1w YAG below 20$...

So making 2W laser is better... Can you please recommend me type of laser ? I wanted to build 2x1W with laser diodes, but 2W diode is quite expensive. isn't hene or CO2 cheaper at that power ?

Hi, i have question about lasers. What happens when I target same spot with 2 laser beams ? Let's saw two 1W laser. Will be final effect equal to one 2W laser ? Thanks

Ah yea, sorry, I was thinking about physicist...

Hi, this may be quite stupid question but I have to ask... How easy is to find a job as physicist... I am currently 18 and next year I'm ending my high school. I was considering to carry on studying IT or physics...As jounger I loved doing stuff with computers, but now I'm quite fed up with...
