This review actually tested the laser's output and found it to be 2mW, which should be fine for pets if you're not pointing it directly into their eyes (which I assume you wouldn't).

My one concern is that green lasers are actually diode pumped solid state lasers which produce green light by frequency-doubling infrared, and some designs can actually emit much more infrared than green. I'm not sure if the author tested for infrared.

Edit: I asked the author about IR and they got 2.1mW@1064nm, with the caveat that the laser power meter may not be very precise at low power levels. That's probably not dangerous.

@tagesschau Warum wurde TRUMPF SE + Co. KG aus Deutschland vergessen? Von denen stammen die Hochleistungslaser für die Belichter!
Könnt ihr ja zwischen die beiden und einfügen.

Could we, one day, watch “The Last Days on Mars” on … Mars? NASA recently beamed messages via laser across a distance of nearly 16 million kilometers as part of its Deep Space Optical Communications experiment. This could open the door to sending scientific information and high-definition imagery and streaming video to and from Mars without significant delay. Science Alert has more: https://flip.it/8XZweF

I would like to buy a laser pointer for my cat, she loves chasing light, but I cannot find a reputable source for quality laser pointers. I don't want to buy one of those trash keychain ones sold at most pet stores, but I also don't want to buy a super powerful one that is too bright for my cat. I'd like something with decent build quality, I don't need it to be rechargeable because I have a ton of rechargeable AA and AAA batteries. Does anyone have a suggestion?
