Below is a table of different wavelengths and what gas combination generate them. See the list after the jump.
Blue laser & Polygon Scanner
Posted in Laser Videos at 10:00 am
Here is a video I made playing with my blue DPSS laser (Wicked Lasers Spyder II) and my polygon scanner from Mi Lasers.
Enjoy!

RGB Scanner Effects
Posted in Laser Videos at 8:05 pm
I’ve had some time to experiment with my new Sypder II BX and I wanted to share another video montage I’ve created. The same three lasers were used in this video as before.
This video shows a close-up for the working laser disc components, beam effects and the projected image. This is my favorite video so far. Check it out!

I created a video of my 3 Wicked Lasers in use at the same time. It took some careful positioning of the beams but I managed to focus all three on the scanner assembly and to project three images at the same time. I used my open loop scanner to project the light and a combination of LaserLine and iTunes (Nine Inch Nails) to produce the image.
The base image was a rotating circle created using laser line. It was then modulated according to the music to create a more visually appealing result. the benefit of this method is that it avoids the diagonal shape that my scanner normally produces.
The effects are amazing! Check it out:

Sonar II Burner
Posted in Laser Photos, Random at 7:38 am
Wow, the guys at Wicked Lasers really know how to make a cool gadget. They have managed to squeeze 60mW out of a blu-ray laser diode and fit it all in a nice little package. I would love to have one of these things! Lighting a match with a green laser is cool, but other people can do it. If you had one of these, you would make all other blu-ray pointers look like toys. Especially the home made ones.
To the best of my knowledge, Wicked Lasers is the only company that offers professionally built blu-ray pointers like this. I’ve heard some horror stories of people trying to do this themselves as well as crap that people have gotten off eBay. I have never heard of anyone managing to get 60mW though!

Different types of lasers
I found a great resource for laser types. Check out the full list after the jump.

Wicked Lasers - lighting a match
Posted in Laser Videos, Reviews at 12:28 pm
Here is a great video I found on YouTube of a Wicked Lasers Nexus series being used to light a match.

Laser Slide Projector
Posted in Random at 6:57 am
This is an interesting post - the inventor uses a laser as a point light source for a projector. Essentially, a lens is used to increase the beam divergence. A slide is inserted between the slide and the laser and the result is a large, sharp image projected. It is monochrome but neat…

For those of you who are not familiar, one of the best laser resources - covering everything from theory to safety, is Sam’s Laser FAQ. I have attached the table of contents here, but the document itself is huge.
