We've all held a laser in our hands , and in close range ,the beam at just 500mw+ is PHENOMENAL but how does it look from range of say... 1-10km away tho? Cos at close range... sure .... the scattering is pretty impressive but is the scattering strong enough to be seen from afar tho? Just...

We often hear about how overdriving a diode will shorten its life , fry the dye and what have you. That I get.. (actually I don't get it technically) What I don't get is how does heat shorten the life of a laser. I mean.. there's no moving parts. Diode, driver , electricity source. Bam ...

Alright , so it's a wrap for the sales of my old CNI PGL-III-C 532nm 500mW laser. With the shutting down of the CNI portable laser branch it might very well be a very rare hobbyist item by 2015 , and its now owned by firelaser. Very prompt payments , quick PM replies and accurate no-nonsense...

Sigh...... I knew this laser hobby is a whirlpool for monnney and I was right... WELP there goes my saving plans. I'm curious about how much would it take for someone with the hands of a pianist to assemble a laser for someone with twigs stapled to burger patties for hands. Starting from the...

So I've been browsing DTR's webpage lately... you know... cos I fear imminent laser market collapse and I find something interesting in the 462nm range. inb4 any judging sets in. I'm a COMPLETE NUB with regards to lasers. I'm not that rich and if I break it assembling something I'm done .. no...

I have an IDEA! You know how back in the 90s and early 2000s all computers are sold in a prepackaged box with fixed hardware that the manufacture think the customers will like after doing extensive market research? In comes Dell who allows the user to design their own computer online and choose...

I just read that CNI will soon be ceasing production of all portable , pointer , handheld , anything that runs of battery power starting 2015. Dragon Laser's 589nm DPSS spartans are also now in "limited supply". Laserglow is also closing production of portable lasers I've heard. With all...

Traditionally when it comes to lasers in excess of power of 1W , the only safe option would be using an all glass G-2 lens for fear that the arcyllic lens may melt as the lens heats up . Now I'm wondering....... why not use another material that won't melt then? There are plenty of glass...

Hello everyone. I'm pretty new to selling lasers on the internet internationally so I need someone to mark if I've fulfilled all the FDA requirements for laser importation into the states. I'm looking at the FDA Laser Import Guidance as we speak. It has quite a few requirements so I'll list...

Now I've recently gotten back into the laser hobby after a long break I've been scooping various laser vendor sites lately.... I'm kinda surprised how little the price has changed. For example a 500mW 532nm DPSS laser still cost almost $500 brand new. A 450nm 1W+ laser still cost upward of...

Hello there everyone , now I understand that lasers are sensitive components and the diodes and the PCB components could easily be damaged by ESD or power surges . Now I've seen people ship motherboards and computer components in an anti-static bag , what I'm curious about is , is it necessary...

Hello everyone , Hammy here, just dropping by with a little suggestion to how reviews can be done. Its by no mean authoritative ,just sharing with the community how I do my reviews. The template below is based on the CNI laser review I did earlier...
