These are burns from a YAG laser going thru a beam expander thereby yielding a larger burn with greater resolution and detail.
The starting point is ‘A’ on the left side. The laser resonator mirrors are quite mis-aligned witnessed by fingernail shaped burns. The white areas are where the energy is the greatest.
The rear mirror was [...]

Here is something new that will quickly facilitate aligning a laser beam centered to optics, apertures, prisms, amplifiers, to mention a few applications.
One old approach was to put a hole in a piece Zap-It alignment paper centering the hole on the item and using a piece of tape to hold the paper in place.
Something new [...]

After doing maintenance or rebuilding a laser, it may be difficult and time consuming to get it to lase properly again. The hardest part is getting the resonator mirrors in position. One method is to set up a HeNe laser to align the mirrors but this can be a lengthy process.
The VW-IR2S product presents a [...]

We extend an invitation to you to write your comments here telling us about how you use the products we offer.
One of our customers partially lines their enclosure with Zap-it laser alignment paper to see if there is any stray laser light. Another one cuts a small hole in the laser paper to clear the [...]

Zap-it Corporation made quite a hit at Laser World of Photonics 2009 with our new product VW-IR2S.
The OEM’s who received samples could readily visualize the application for this product in their labs. Several asked for variations of the product which we will be considering. Some were very creative in mentioning how they would use the [...]

It’s always exciting to see so many laser equipment and component manufacturers in one place at one time. Although the economy is down in most of the world, there seems to be as many exhibitors as usual, if not a few more, but the display size appears to be smaller. Laser Components from Germany was [...]

The femtosecond laser (aka ultrafast laser) and incandescent light bulbs combine for a brighter future with no increase of power consumed by the incandescent light bulb while generates a brighter light.
This is another excellent example of what lasers can do to make a better, greener life for day to day situations. Chunlei Guo and his [...]

Ever built a laser or replaced a resonator part while servicing a laser? Both situations can leave you with a laser that just won’t lase. I’ve been in these situations and spent many hours adjusting the resonator mirror(s) looking for alignment to get it to lase. If the laser you are bringing to life is [...]

I have not had the pleasure of meeting Dr. Ted Maiman. His accomplishments laid the foundation for what the laser industry is today. In 1960 he demonstrated and patented the first working laser. The laser was a helical xenon flash lamp with a Ruby rod placed in its center. The Ruby rod was coated with [...]

It often interests me to think about how laser accidents occur.
I was involved in two accidents. Thankfully, there have only been two that have involved me!
In one, the laser beam burned my plastic laser eyewear frame and the edge of my nose. It was 1971 and I was in a lab trying to adjust the [...]
