…(at risk of peppering a bunch of innocently-occupied rooms in the process)…

Just to repeat, then I’m out (don’t want it to get too “political”).

Political? Ok? :person_facepalming:

Just like if you use said laser… you hit your target or blind a bunch of innocent people…. right??

The same thing applies to Pb & Cu…. hit your target, whatever it may be.

With either one, you do not do it unless you know you can hit what your aiming at.

I’ll be out to I guess…
…………would not want to offend or tip off any potential bad guys.

Questions (not being sarcastic and also not suggesting it’s a good idea either):
Would the buildings glass not stop said laser from hurting people behind it (so only the shot out window rooms occupants were at risk)?

Would the buildings glass reflect the laser and have it still be powerful enough to do damage to people still on the ground?

Class 3B
LASER RADIATION
AVOID EXPOSURE TO BEAM
CLASS 3B LASER PRODUCT

A Class 3B laser is hazardous if the eye is exposed directly, but diffuse reflections such as those from paper or other matte surfaces are not harmful. The AEL for continuous lasers in the wavelength range from 315 nm to far infrared is 0.5 W. For pulsed lasers between 400 and 700 nm, the limit is 30 mJ. Other limits apply to other wavelengths and to ultrashort pulsed lasers. Protective eyewear is typically required where direct viewing of a class 3B laser beam may occur. Class-3B lasers must be equipped with a key switch and a safety interlock. Class 3B lasers are used inside CD and DVD writers, although the writer unit itself is class 1 because the laser light cannot leave the unit.

Class 4
LASER RADIATION
AVOID EYE OR SKIN EXPOSURE TO
DIRECT OR SCATTERED RADIATION
CLASS 4 LASER PRODUCT

Class 4 is the highest and most dangerous class of laser, including all lasers that exceed the Class 3B AEL. By definition, a class 4 laser can burn the skin, or cause devastating and permanent eye damage as a result of direct, diffuse or indirect beam viewing. These lasers may ignite combustible materials, and thus may represent a fire risk. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces – meaning that great care must be taken to control the beam path. Class 4 lasers must be equipped with a key switch and a safety interlock. Most industrial, scientific, military, and medical lasers are in this category. Medical lasers can have divergent emissions and require awareness of nominal ocular hazard distance (NOHD) and nominal ocular hazard area (NOHA).[20]

Pretty sure the power and wavelength would put this far into Class 4, meaning it can mess your day up with even a diffuse reflection

Makes me laugh that they’ve made it illegal to use & export above 5mw lasers but you can have as many guns as you like.

Obvious troll since UK has some of the most strict gun laws

[Nev]

I was talking about USA
I have a 50mw ,37mw & 17mw lasers , they had to be sent on the QT.

Discussions about gun control derail in seconds, better not to go into that.

Hey, you’ve been around, and you’ve seen how quickly these threads devolve. :confounded:

And all too often it happens overnight and I miss all the juicy bits. :laughing:

If only everyone used Anduril (swords) we wouldn’t need gun control but alas, we have Nev.

[Nev]

Lol
Trolls with swords , now that’s dangerous

[Nev]

Lasers.

[Nev]

Two of my lasers were cherry picked by howie glatter from New York, after being in the freezer for an hour ,they still work & still very bright , my other one doesn’t like working if it’s 5*C below room temperature.

What do you use them for?

[Nev]

I could say mind your own business but I’m not like that .

Astronomy
Or as my missus puts it NERDING. lol

[contactcr]

I think I saw some of your people when I visited the observatory near me. They just use them for pointing things out right?

(and impressing Astronomy girls obv)

[Nev]

the Middle one is my missus, & I’ve done the other two

No , well some do (point things out to newbys) I use them attached to my telescopes with a remote switch and use them instead of or aswell as a finderscope. Space is quite big youknow, it’s not easy finding stuff with a 1/2 degree or less field of view.

Edit

notice I exercised a lot of self control & didn’t even mention Big Bang.

It’s not on the “QT” anymore mate…. you just announced it to the world. :person_facepalming:

What if Boris happens to be a member here & reads this?? .
