    Sanwu '3000mw'

    After hearing a lot of good things about Sanwu, I bit the bullet and ordered a blue 304 model rated at 3000mw, with 2 x 3.7v lithium batteries. The outcome was a little disappointing.... The batteries appeared to be rechargeables, and not fully charged at that. The laser itself – solid, heavy...

    laserpen aimed at apache helicopter -- arrest followed

    Hah hah - now there's a thought. Ship over a bunch of laser pens with "Danger - do not point at helicopters" written in Afghan on them, and modify missiles to home in on 532nm. That would end the war in about a week.

    laserpen aimed at apache helicopter -- arrest followed

    Maybe, just MAYBE... you don't want to point a laser pen at a helicopter gunship, crammed with detection equipment, piloted by trained observers, and armed to the teeth with missiles...

    Violet-emitting laser pointers now commercial.

    I've actually ordered two - a 5mw and a 100mw. I'll report back when they arrive...

    Better yet, DealExtreme are chopping them out for a mere $23! http://www.dealextreme.com/products.dx/category.923

    Boeing's airborne tactical laser

    You can just see some kid in a Manchester housing estate pointing his 20mw greenie at a plane... the WRONG plane... "Permission to return fire?" "Ooh yus!"

    Green Laser Hits Police Chopper Pilot In Eye

    I think you've hit the nail on the head, here. These reports tend to be of the flimsiest variety, seldom citing details and perpetuating the myth that a handheld device can do anything up to and including blowing up a planet.* I'd like to see a report on this - surely it generates enough...

    Green Laser Hits Police Chopper Pilot In Eye

    You know, these stories bother me. There have been about a dozen so far this year with variations on the green laser / police helicopter / commercial airliner etc and they all have one thing in common; a near-superhuman feat of aiming a laser with startlingly low beam divergence. Consider: The...

    Vital Spirt - are they still good???

    I used to buy Leadlight 105s from them, before they started coming with APC built in. I would vouch for Vitalspirtit unreservedly - very good customer service, great comms and fast delivery.

    Blu-Ray drives that rock for lasers

    How dare you! I'm a one-forum sort of guy!

    Blu-Ray drives that rock for lasers

    I'm considering getting a few Blu-Ray drives to take apart for the diode-y goodness within. Any recommendations for bulk (well, around five) buys? I'd rather have the drives than the assemblies since I'd put at least one of them into my PC...

    100mw Greenie for £20?

    Noted with thanks. I read the reviews after posting and decided not to buy. Still - the unmodded 50mw version is not a bad buy for a cheap greenie.

    Australian laser laws - what is the latest news???

    It's fair to say that tabloid journalism is not a career that requires a solid grounding in coherent optics...

    100mw Greenie for £20?

    I'm tempted by this beastie: http://www.dealextreme.com/details.dx/sku.13446 I've bought quite a few of the DX 100mw red lasers, which I thought were excellent value for money, so may go for one of these... or even three, given the discount!

    Home hologram kit

    You're right, of course. I've since found out that the supplied laser outputs at 635nm, and my HeNe outputs at 632.5nm, so it's eminently do-able... Maybe I'll order some film and see how I get on.
