Is 0.625 Divergence and a nice round dot at 80m better than should be expected from a $15 Green Laser 532nm 80mW DPSS ?

After doing some testing on my "Hammer" with the new NUBM44-81 diode i figured out the cylindrical lens pair wasn't aligned as good as it could be which i was pretty sure was because of the "rails" had issues because i used tooth picks for them.... So i removed them and cleaned the tube and...

Right now it's just a prototype to see how well the two lenses work together but judging from my "across the room test" it's going to work VERY good because from across the room the spot is like the head of a pin !!! So far, So GREAT !

These are some high rez desktops/wallpapers i made from my former hobby of doing restoration & repair work and collecting Bulova Accutron 214 "tuning fork" wrist watches from 1960 through 1976 and I'd like to share them with anyone who might find them interesting, These images are from the...

Laser needle ? Yep ! CsMko1aOsOQ

Yes you read that right, Diamond Superlasers ! qiAtCLHFep8

Especially if you take them to full screen on a big screen TV ! Look at the center for best effect !

As some of you may or not know the NUBM44 diode has gone through a revision to NUBM44-81 from the superseded NUBM44-71, I've read that some people have reported the the new NUBM44-81 may have a power output of 8 watts plus at 4.5 amps, Has anybody been able to confirm this with some power meter...

While i'm working on getting my 7 watt "Hammer" back up and running it's on hold for a little bit BUT in the mean time i was messing around with my thor saber and the thought occurred to me that i have some left over Cyl lenses so i set up a 2X pair in a tube similar to what i did for the...

How does a collimator take the uncollimated light that is highly diverging and turn it into a narrow column of collimated light that is hardly diverging ? Opps in the lower right hand corner is meant to say "collimated light" and of course the collimated light is diverging some....

My 7 watter diode's glass window unbounded and while trying to do something about it i killed it, It's going to be a very long time before i'll be able to do anything about it.....

I made a Minions Mini Movie with scenes from the movie Despicable Me 3 and i have it unlisted on Youtube for the members here only if anyone would like to check it out, It's pretty funny stuff ! Q-tnG46J4p4

I just got done measuring all the beam sizes focused to infinity at zero and out to 175 feet and here is what I got..... And from what many people have told me in the past numbers that low are unbelievable, Can someone please tell me what I'm doing wrong ???

I have always known there is a laser reflector we put on the moon surface but I didn't know it is what's called a "Retroreflector" which can reflect laser light back to it's source from any angle it hits the reflector ! Pretty cool stuff ! They use a 1 GIGAWATT LASER ! I gota get me one of...

I have two lenses that have some unusual properties to them and I'm curious about what these unusual properties do. The first is a double concave lens but one side is curved more than the other, What does this do ? And the other is a doublet lens with two lenses glued together, Why ? And the...

A short video explaning what "Doped" YAGs are and how they are used to make different color laser light....... 6juE_l84Nq0

I had this happen just now and I'm thinking there is likely only one cause, Some sort of contamination somehow got on the lens and got fried which cracked the lens ??? It's a DTR G-2 and luckily I have a few of them on hand, Anyone come across this before ???
