CVI Melles Griot is giving away a very cool, well made tee shirt to celebrate the 50th anniversary of the laser. All you have to do is provide a short story about how you interact with lasers. You actually type it right into the web form. You can look at all of the stories that were submitted on...

If anyone is interested (and can take time off from the WL Arctic drama), there is a free webcast on 7/27 regarding high powered lasers in defense applications. Yes, you have to register; but it's free and completely legit (hosted by Laser Focus World). The presenter is the editor of Laser Focus...

This is truly one of the coolest things that you can show elementary school children with just 5mW of power. It's a great experiment with lots of "WOW" factor. Bill

Maybe with 1 watt of 445 there would be flaming water fleas followed by a melting eye dropper......

Try using a Wicked core or another 5mW 532. Bill

Here is the experiment done by Arbor Scientific. The narrator unfortunately misidentifies the wavelength of the laser; but the experiment works perfectly. The water acts as a small lens and assists in magnification. Bill YouTube - Green Laser Microscope

Marijuana makes you crave sugar. Now we will have to obtain our soda from the underground black market. $65 for a can of Mountain Dew! Actually, NJ banned soda, energy drinks and candy from all vending machines on the properties of any K-12 schools that receive state funding (all public schools)...

Welcome, I'm in West Trenton. It was a good idea to be frugal with power levels until you become more proficient in the hobby. The eyes of the uninformed are easily self compromised. Bill

I am used to putting a laser without aperture cap into a ziplock baggie to keep dust off of the lens. This incident was with an LED shoppe 532nm 50mW with the push button switch that must be depressed constantly. I reached into my pocket and unaware that the laser was actually pointing up, I...

Re: FS: 445 Custom Focus Knob / or EzFocus Adapter for AixiZ Glass Lenses I'm told that the new AixiZ lenses are coated for 405-450 and will increase performance by 15% over the normal AixiZ glass lens. I wonder if the size specs will be the same. Bill

Hey guys, It was me who got the other LaserPhysics Reliant 50S-488 from Timelablasers. (Thanks again Rob!) I'll meter, photo and review it as soon as work lets up. The laser took a fun 4 day trip through US Customs, Homeland Security and the FDA/CDRH with queries at each juncture. You should...

I think that I live near c0ldshadow (West Trenton, NJ) Who else is in NJ? Bill

I was just on Photonlexicon and their 445 thread is up and running again. Bill

It's best to get rated, certified eye protection. With discount eye protection you might put your eyes in compromise. Damage can be permanent. Don't take a chance with your eyes. You only get two..... Bill

You only have one set of eyes. I would not take a chance with glasses that were made for a different purpose. (They might work....). Get certified laser eye protection. Consider how much you paid for your laser. Your eyes are worth way more than that. One shot or close reflection to the eye is...

Check out the attached link. Next time I cut myself, I'll just reach for my handy 532nm jayrob pocket mini. The Wellman Center for Photomedicine: Faculty Laboratories

Re: Optotronics Blue RPL-70 $300 If I remember correctly, Bryce sent this laser back to Optotronics for repairs. Do you know what repairs were done and what the general evaluation of the laser was? This laser is like a hot potato; no one wants to hold it for too long; but there is a strange...

Thanks Jerry, That thread must have eluded me. I like seeing them smoke & die. I think that I'll take out my 450mW CNI baton and sear a few tonight. Bill

Wow, Mosquitos don't stand a chance against 405nm. Check out this video. You can almost smell the last sequence. Bill YouTube - Mosquito killed by a Laser
