And it tends to get really ugly when believers try to run a country according to their superstition with no regards to other's ideas.

I can't disagree more. The swine's are making a nice profit selling laser with blatantly dishonest claims. Barring any public agency to keep an eye on them the only way to stop it is either private litigation or people like us to cut into their profits with LPMs.

Last I heard a human at rest would produce app. 100W. Some of the heat would be disposed of as heated breathing air, some by air heated by skin contact and some as blackbody radiation. I have had the opportunity to handle some really fancy thermal binoculars and seen the thermal signature of a...

The wrong item is kind of outside of contract, the seller have just accidentally mailed some of their property to you. It is still their property and you should return it on their expense, if they desire so. If you happen to be sending them something else on your own expense* and it would fit...

The 20 sec is the crystal setup being warmed up to working temperature. A poor quality laser is very likely to have such issues and it is more or less impossible to fix.

I agree with rhd and can inform you that honest shops follow those procedures. I had a order from surplusshed with one item wrong, when I contacted them they went ooops. and shipped the correct one. There were no mentioning of returning the wrong item, likely because it was less than shipping...

It sounds like you are mistaking the initial reading for initial laser output. The meter works on the temperature difference between the sensor and the cooling plate it is mounted on, it will take some time for the laser to heat the mass of the sensor and show true power. Your 445nm laser does...

Well it is simply a combination of poor quality control and the US limitation of 5mW on import lasers. It means that the really low end crystal setups will be sold as 5mW no matter what they produce.

Thanks for the heads up. I am used to honest dealings over the net and find the Laserman behaviour inexcusable.

One problem is that low cost 0-50mW lasers, particular pen-style are rarely power tested. You could just as well buy 5mW pens from ebay, they will be somewhere between 1 and 40-50mw. I recommend that you get some goggles and a good quality tested first laser. Laser Safety Goggles EP1 For...

daguin, It looks like you are working towards Pascal's wager. The idea is that since hell is eternal it is a good bet to worship on the chance that god is real. I strongly suspect it was meant as a joke, as Odin* is not likely to be impressed by any ones christian prayers. :) *Or Jupiter...

How about you just lower your expectations of that pen down to 1mW level? My signature contain a link to Odicforce, it is in the UK and carry good quality products. Don't forget goggles for anything above 5mW. They tend to cost more than the laser, and if you don't want to spend that much get...

I am not sure how relevant it is by now, but I am pretty sure one of those apostles were reported martyred 3-4 times in different locations. So even the somewhat irrelevant point of them really believing in jesus is in doubt.

Odicforce is in the UK. I have these myself. http://odicforce.com/shop/article_OFL52/Laser-Safety-Goggles-EP1-For-190-540nm-_-800-2000nm-%28Green%2C-IR-and-Blu-ray-Lasers%29.html?shop_param=cid%3D20%26aid%3DOFL52%26

I don't think that advice were appreciated. :crackup::crackup::crackup::crackup:
