Marking and Engraving Across All Industries

Why I was slow to return calls last week

Ok here is my big question for all you Photonics buffs and Laser geeks:

My friend Tim takes a high speed photo of the eclipse and it looks like the first one. You see a small inner Corona, and even some red prominences.  They stream away from the sun though there is a hint of red rolling over the moon.  My photo (the second) was taken with a longer exposure and captures both the inner and outer Corona, (with a clean dividing line). But look what happened to the prominences!   They defused over the surface of the moon.

Can some one explain how this happens. The moon has no atmosphere and the sun is 93 million miles behind it.  Was it diffraction of the light passing over the tips of the mountains  on the moon?  Or was it like my daughter Miesha explained: “The Red was wax wrapping around the green cheese”.

As for the experience of the totality itself:

The Dark comes on fast. In a blink it swept past the hills near by and, before I could turn around, covered the ones in the distance. Actually noticed Jupiter first as I turn back and then saw that orb that captivates.   Tom recalls the sudden drop in temperature; Stan called it life changing as the birds went silent.

5000 feet up in a forest opening with a few hundred campers in Malheur National Forest in Oregon. A make shift city sprung up as all the campsites were gone a week ago. Good people, friends, and their family.  (I’m standing behind Amir and Dusanka)

3 guys, 1500 miles in a rented sensational Ford Expedition, 3 nights, and incredible memories.  Plus the last night in Reno was OK too.

Medical Titanium Colors

titanium-colorsLaser Mark’s Company has just entered into a licensing agreement with Crashtag to provide the widest range of colors on medical grade titanium.   While some titanium colors are easy to achieve, Crashtag has spent the past year to extend the rainbow of color options including the difficult to achieve Green.  All the formulas were created on a Laser Mark’s Company customized Model 2016-1064 marking system.   The optics and laser mode have been optimized to provide pure oxide colors with the least diffraction effects. Laser systems can be built in Laser Mark’s Standard Class I enclosures, or built directly onto existing production lines.   Our agreement with Crashtag enables them to provide installation training of their proprietary color formulas.  This partnership insures the most  rapid adoption of this technology onto a stable production platform.  Contact Laser Mark’s Company for further details.

Specialty Pistol Engraving with MOPA lasers at Laser Mark’s

police-range glock-dark-marking-sj-police-logo glock-swat-dark-marking-on-slide marine-logo

Laser Mark’s Company is proud to be the engraver of choice for many local law enforcement professionals. Our MOPA laser system can be programmed to etch, burn, lighten, or smooth. The logo is permanently marked and blends into the natural gunmetal background for tactical safety. We custom redraw logos from many artworks and even patches to make the finest use of our MOPA lasers capabilities. While this may be more time consuming, the quality of the effort shows off the pride of our first responders.

Laser Mark’s Company is happy to provide this service to any licensed individuals as well.  Some of our engraving requests have been quite creative.

Precision, artistic, and permanent marking on many different surfaces. Laser Engraving will never replace traditional scroll work from an artisan. Yet laser marking adds the ability to rapidly make custom designs.  Adding pulse control from MOPA Fiber Lasers allows for variable depths, remelts, textures, and contrasts.   AR-15 Receivers are marked with a the “211” Division logo of the SJ Police. The same logo was etched onto a wood stock for a gift for the retiring Lieutenant as well as the M1911 belonging to the Desk Sergeant. And note the Cross on the Glock21 slide. Zoom in on the photo and note that  the engraving is both  deep and smooth.  This is due to the versatility of MOPA wave forms which can create a clean surface that does not attract rust.  Laser Mark’s Company has all the tools!

Gold Marking on Electronic Packaging

Finally a Gold marking process that does not remove the plating!  Electronic devices are plated with 50 micro inches of Gold over 200 micro inches of Nickel.  All previous attempts at laser marking vaporized both Gold and Nickel exposing the base metal Kovar which corrodes.  The Laser Mark’s Company “Light Touch” process just kisses the top layer at the point of coupling and then stops reaction.  This is why it is critical to define that transition point between reflection and laser coupling.   The process is made possible using the magic of Wave Forms on the MOPA fiber lasers.   The pulse width is shortened, and the power density is increased such that only the top surface of the gold is ablated.  This process is perfect for military, aerospace, and other devices destined for harsh environments.  Process is also possible with the new SPI EP-S-J series of lasers

Laser Mark’s Company Retires last Flashlamp YAG

Yes, the old Lee lasers have been put out to pasture.  (Actually they were sold off to a research institute at a university).   All our 1064nm lasers are now solid state.  This means no more variability in the quality of the mark as the lamps degrade over time.   All Laser Mark’s Company machines are now maintenance free.  That eliminates down time and makes pulse to pulse stability issues a thing of the past.   All laser pulses now are clones of each other.   We are the only job shop in Silicon Valley to be fully solid state in 1064nm and our CO2 system is sealed as well.   Come to Laser Mark’s Company for reliability and quick turn production.
