Aircraft laser strikes hit new record with 20 incidents in one night

Re: Dangerous, stupid and highly illegal"

I'm 70 miles (100km) from a major metropolitan airport, their primary approach vector was consolidated about a year ago to a single path over the mountains, and the folks a couple miles south of me, who live in a very remote rural and quiet canyon, are quite annoyed at the non-stop stream of big jets , spaced 30 seconds apart all day and night that now fly directly over them. as this valley is up 1000' elevation from sea level, the planes are flying at 6000 or 7000' above sea level, they can be quite loud.

that all said, to the topic at hand.... green laser pointers. I'm an amateur astronomer, and use these at public events to point out the night sky features we're showing the public. There's a new generation of these lasers that are WAY brighter than advertised... I bought a pair of supposedly 5mW green lasers, that are easily 30-40 mW compared with my old 5mw lasers. the older ones used 2 AAA batteries, and were quite sensitive to cold and low voltage, they'd stop working if the batteries drop below 1.4V each (2.8V total). These new 'laser 303' lasers use 18650 LiIon rechargables. I measured the electrical power consumption of one at 1.2 watts, and at the typical efficiencies of the IR diodes, IR laser crystal, and frequency-doubler crystal these use, that comes to 30-40mW actual radiated power. frankly, for my star pointer use, I preferred the old 'actually' 4-5mW lasers, but their battery consumption was ridiculous.

I suspect this increasing stream of reports in the press will be followed by banning them entirely.
