The Federal Aviation Administration says four pilots reported laser lights filing their cockpits in the skies above the Valley, Tuesday.
The incidents occurred between 6:30 p.m. and 8:50 p.m. while the aircraft were headed to Deer Valley Airport, according to the FAA.
In each case, Phoenix police and the FAA were notified.
New numbers from the FAA show 183 laser like strikes have been reported in 2015, that's more than double the number reported in 2014.
Officials say there may be a reason why laser strikes are happening more often.
"I think the availability, of more lasers, and the inexpensive purchasing of one," said Art Rosen, a private pilot in Scottsdale.
"Nine dollars is what a green laser costs and these are the ones that are causing all the problems," explained Rosen.
Rosen says shining a laser and blinding pilots should be treated as attempted murder. He says a temporary, or worse, a prolonged moment of blindness in the air, can mean disaster.
Right now, if you're caught shining lasers you could face 20 years in prison and a $250,000 fine.
Phoenix police say, when a laser strike is reported in city limits, they have the resources including the helicopter and ground units to zero in on suspects.
