Cheap YELLOW/ORANGE laser!
Posted in Random at 6:40 am
I’ve been looking at buying a 593.5nm yellow / orange laser before and after a lot of research, Tech Lasers has a great price of $299. This is really tempting….
Does anyone have one? Please leave your feedback on it in the comments!
From their page:
Synthesized from two separate laser beams, a 1064nm and a 1342nm laser beam, the Xerex orange laser is a landmark in Laser technology with its unprecedented use of micro diodes to produce a vivid 593.5nm orange beam. It is truly a magnificent rare new technology that’s a must have for laser pointer collectors.

A Spyder III is in the works!
Posted in Random at 10:30 pm
I just got a message in my inbox that Wicked Lasers is working on a 3rd verison of their powerful Spyder series. For those who didn’t get the email, the message is below:
Oh yea, AND YOU CAN WIN ONE
Hi Laser Community,
It’s time for The YouTube Challenge! Pull that video recorder out of that closet and get those batteries charging. We’re looking for creative videos to place on the homepage of Laser Community. The videos could be funny, artistic, or could even be a Wicked Lasers commercial showcasing our lasers. Get this, the GRAND WINNER will receive the not yet released Spyder III laser unit with an average output of above 400mW!! For more information, please visit http://www.lasercommunity.com/the-youtube-challenge-win-a-spyder-iii-laser-t16970.html.
Good Luck,
Wicked Lasers
Nonlinear Optics / KTP
I just found a great article on how frequency doubling works in nonlinear optics. This is the process that is used to create your 532nm lasers (among other colors.) Below is a brief summary of the article. Check out the links for more information. Read the rest of this entry »

My batteries came today! They need several hours to charge but I managed to take a few photos and make a short video. View my post for my thoughts on this great laser.

Spyder II BX
Posted in Reviews at 10:18 pm
It is here. The Wicked Lasers Spyder II BX. A high power, hand held 100% duty cycle blue laser. This isn’t a toy.
I don’t have batteries for the laser - yet! Once I do I will post a full review and plenty of photos and videos. More to come in the next few days - check back!
UPDATE: I now have a few photos online. See them here Read the rest of this entry »
Different types of lasers
I found a great resource for laser types. Check out the full list after the jump.

How to “write” with your laser
Posted in Random at 9:49 pm
This author has some helpful tips with how to write using laser light and a digital camera. I’ve tried this with limited success. For something like this, a lower-power laser works best. I’ve foudn that something like a Nexus overpowers the timed exposure on the camera.
