Stupid laser fun

Pointless laser tomfoolery. I cite this as about the most aggressively useless thing one can do with a laser. This is some fun I had about a year back (before I started making holograms) with two tiny mirrors, two tiny DC motors, a pair of rheostats and a 15mW DPSS laser module. Relative changes in motor RPM create the different patterns... yay.

dpss? diode pumped solid state

what does that mean in lasers

[69justin69]

The "diode" part of DPSS refers to the pump light source. In the case of a DPSS greenie, it is an infared diode.

The SS (solid state) simply means that the lasing material (cavity) is composed of nifty crystals and not a gas mixture like one would find in an argon or helium-neon laser.

so does the DPSS laser appear brighter than regular lasers?

[69justin69]

"Brightness" of a laser is something of a subjective thing. The majority of what makes a laser beam visible is the output power (generally measured in milliwatts [mW]).

One will also find, however, that when comparing visibility of a green laser of equal output power to say, a red laser, that the green laser light will appear "brighter". This is because the human eye is more sensitive to green light than it is to other wavelengths.

compared to the laser crapb - for 20 odd quid - its not that bad - theeffects are quite good - what do you expect for £20

nice vid

i got one of these but in a red , beam , its called the laser crab,

it reacts to music , if u sit it on a speaker it rocks out wickedly, combine it with a small mirror ball .smoke machine,and u can transform a party dance floor

[deafbonnie]

cool!! i wanna play too!

[dontaskwhyplz]

or you could just get a laser pointer...

[minousoft]

these are fun to play around with, especially if you build them into a gun. i did that once and people thought it was neat that I could project a laser anywhere

good for night clubs and shit :D
