I'm new to lasers. I'm primarily interested in small handheld green lasers for use in competitive shooting. 5mW green laser pointers are fairly inadequate for outdoor use in direct sunlight so the wheels have been turning in my head.
Welcome and enjoy the forum.
Use the LPF search function to access the LPF database for answers to many questions . Remember safety use and laser goggles to protect you eyes comes first.
You would need several Watts of laser output to see the beam in direct sunlight. Unless you A) don't want something handheld and B) have several thousand dollars to spend, you're not going to get something with a visible beam in direct sunlight. see thread: https://laserpointerforums.com/f45/visible-daylight-100083.html
Lasers over 5mW are illegal to sell in USA so....
"FDA regulates all laser products, even handheld, battery-powered lasers that are available for purchase FROM manufacturers, importers, assemblers, dealers or distributors in the United States and its territories. FDA requires that manufacturers of these lasers limit the power of the laser light to 5 milliWatts (often abbreviated as "mW") or less. Do not purchase a handheld, battery-powered laser labeled with hazard Class IIIb, Class IV, Class 1M, Class 2M, Class 3B or Class 4 unless the manufacturer has an approval from FDA (called a "variance") to allow the purchase. Lasers approved for purchase in these classes often have very specific uses and may be sold under certain conditions known to the manufacturer. Sales without a variance, or sales that violate the conditions of the variance, ARE ILLEGAL."
Do you need to see the beam for competitive shooting Alex? Otherwise people would have to install these onto their guns.
A nice 10W unit should do the trick.
But to have a bright spot in daylight, you'd need around 50mW exceeding the safe limit by 10x. You shouldn't use Class 3B/4's for gun sights, and they will be disallowed in the competitions too I gather.
Better to stick with those 5mW's IMO.
