That's a very interesting and worrying report.

Up at ~Watt powers and with a telescope, and close to the source, then it would become an issue. If people are doing this close enough and with...

Deptrai,

I'd be very surprised if anyone onboard an aircraft had corneal damage from being shone on with lasers, unless they were disoriented as a result and stuck something into their eye.

Multi-barrel laser cannon & tracking

If the scrote can coalign a pack of lasers to point within 10m at 10km, maybe he should be able to get a good job instead of endangering people. If anything, having several lasers just makes him more...

Laser event recorders

There was a BBC story about the devices, and they do exist, doing coarse frequency spectroscopy and time series analysis. Even if the scrotes don't believe they exist, are they willing to take the...

Identifying a particular laser

Police aircraft carry spectrographs that can give a very good idea of whether the laser the scrote is arrested with is the one that was shone at the aircraft, if everyone has the time and...

IR l@ser emission shouldn't be a problem

If there is infrared laser light coming in, it will be substantially blocked by the windows, so it shouldn't be too dangerous in itself. You eyes will still reflexively track to the bright green...

1W is serious

Pointers are usually 1-5mW, maybe 10mW at the extreme.

1W is serious, especially at green where the eye's response is most sensitive.
I've no idea what a legitimate use of such a device would...

Blinding l@sers

Airship,

That's one of the incongruous laws of war. My understanding is that it originates from a post-WWI ban on `blinding weapons', which was intended to prevent the recurrence of the use of...

250 + 85 +15 pounds?

The magistrate would seem to be suffering from some kind of dementia to accept the kitten story.

If the convict was indeed `playing with kittens', then the illumination of the helicopter would...

Red-finder scope vs mW l@ser

Green-dot:

Red-dot HUDs are great for someone looking down the pointing direction of a telescope, but not to guide the eyes of a class-sized crowd standing around.

I've asked this before, but...

Legitimate use of l@zers in the sky

adamnaylor #120,

You're far from alone in using 5mW class pointers - #41 does, and my #63 also describes uses of potentially dangerous 10-100W yellow lasers by professional astronomers to...

Cures for the l@zer epidemic

It sounds like arrivals over British urban areas are seeing this more and more often. Even if it is simply a larger reporting fraction, the consequences for safety are very significant. I am sure the...

How bright?

Pointers are in the milliWatt range. Disco l@zers are in the Watt range. All are distracting if shone into your eyes, and disco l@zers could be damaging.

However, even with a launch telescope, it...

Astronomy l@zers

There are two very distinct classes of l@zers that might be used by

The first is a classroom l@zer pointer used to highlight sights in the
sky for a huddle of people at night,...
