A 22-year-old man from Greenfield, Flintshire was given a suspended sentence on January 9 2014 for aiming a laser in a “persistent and prolonged laser attack” on a North Wales Police helicopter.
On September 25 2013, the helicopter was called to find a missing person. The pilot was hovering at 1,200 feet over a densely populated area of Greenfield when a green laser beam targeted the aircraft. Over an eight-minute period, the aircraft was hit about ten times by the beam. The majority hit the outside of the helicopter though a video recording showed the interior illuminated for a couple of seconds.
While the helicopter maneuvered to avoid the laser, the missing-person search was not abandoned. No emergency or evasive action was taken, and the captain was in full control throughout the incident. However, the attack distracted the crew, caused distress and wasted search time and resources, according to the prosecutor.
The three-man crew identified the source location and directed ground officers to the home of Kevin Mark Griffiths. He pretended to be asleep and later produced the laser from a bedroom. He told police he had purchased the laser while on vacation in Spain.
Griffiths said it was a “foolish, impulsive and reckless action,” aiming at what he knew was a police helicopter.
At trial Griffiths admitted a charge of recklessly endangering an aircraft or persons inside. He was given a five-month prison sentence suspended for 12 months, ordered to do 200 hours of unpaid work, and was fined £165 in costs.

There are numerous laser pointers in markets, but for stargazing, 50mW green laser pointer is no doubt the best tool for amateur astronomer and astronomical enthusiasts.

1.Why choose green laser pointer?

As we know, there are four visible colors laser pointers in total, which are blue violet, blue, green and red. One should know that green color is the most sensitive color to human’s eyes, it is 7 times visible than other colors in the same output power. That means, one 5mW green laser pointer seems 7 times brighter than one 5mW blue violet/blue/red laser pointer. In the dark night, green color laser pointer is easily to catch one’s attention and allow you to follow the dazzling forest green line to see far away stars or constellation. It is amazing to own this tool.

2.Why choose 50mW laser pointer?

mW is abbreviation of milliwatt, which is optical output instead of electrical input. The higher the output power, the more shining the laser pointer, at the same time, the more dangerous it is. According to laser pointer safety classified level, 50mW belongs to class IIIB. This level is relatively safe to human with proper caution. And the beam is bright enough to point at stars or other celestial objects.

3.How much of a 50mW 532nm green laser pointer costs?

It is usually USD $70~80 per piece of a 50mW 532nm green laser pointer from reliable supplier.

One need to pay much attention to the quality of the laser pointer, including diode, material, cooling system, guarantee time etc. Some black-hearted manufacture use second-hand diode to gain much more profits, which hurt customer’s right and health deeply.

And one also need to notice 50mW is harmful without suitable use and protection. Do not point at eyes or stare at the beam directly and leave it from Children.

Enjoy your stargazing laser time with the 50mW 532 nm green laser pointer.
