Possible laser being pointed at lenses to avoid detection?

I have a sneaking suspicion that someone is sneaking in and out of my house. Is it possible that they are using a laser, someone inside, to block the detection of someone entering, and then doing the same when they leave?

1st time it did it.

I literally thought I heard the door open and close each time that this happened

2nd time it did it

A glasses or camera that's sees lasers

Are there passive or active glasses that can see lasers that are invisible to human eye, like in the movies when a burglar goes into museum and it looks like there's no security, but when he puts some glasses on, the lasers security in the room suddenly becomes visible to him

If yes, any link to that kind of glasses?

Continue laser or go for electrolysis?

Im 23F with pcos, ive been getting face hair laser for about a year now. Though the density of my hair has reduced there are some strands coming in coarser than before. This has shattered my confidence and i have to shave every other week. Should i ditch face laser and go for electrolysis or continue with laser? Im scared of getting scars from electrolysis as well. Also, do you think this is paradoxical hypertrichosis? I cant tell since i dont have before photos...

Quick question

So how expensive would a green laser need to be to...lets say blind a flock camera? Thought i would ask the laser people...remember this is only for scientific purposes, nothing more i swear, totally not for anything else...

Machine : Lumenis. 2 years ago I got 12 times package for arms and hair hasn’t grown back for most of arm parts.

But in another center, I use the same machine but am going pretty irregularly, and hair keeps growing back all the same.

Can some professionals tell me what really matters ? The energy settings or the consistency of getting it done ?

Thanks.

Any good class 4 ir laserz

Looking for class 4 IR lasers for a minute now and usually when I find one that looks good. It leads to a Chinese website. That's almost always a scam or there's stuff wrong with it, can you guys recommend a lase? I can buy that comes fully built and can be used as an igniter?

UltraPulse TotalFX Co2 Laser by Lumenis

Has anyone had atrophic acne scar revision using this specific laser? I’m hoping to have it done by a local board certified dermatologist this Fall or Winter. I’ve done various microneedling treatments (mild improvement) and a Cool Peel (zero improvement), and a round of Accutane (complete eradication of acne). Some of these are more than 20 years old, a few are 10 years old or so. ETA: Picture 1 is right cheek and picture 2 is left cheek (before laser).

For MOPA fiber laser users — how are you handling multi-colour layer setup in LightBurn?

Question specifically for those doing colour marking work on MOPA fiber lasers — if that's not your setup feel free to ignore this one.

Each colour in a design needs its own LightBurn layer with different pulse width, frequency, speed, and power settings. A single image can easily need 15-20+ layers, and right now I'm building all of that by hand every time.

Wondering if anyone's landed on a faster workflow for this, or if manual setup is just the standard approach. Would love to hear how others are handling it.
