Expert and his associates are experts in laser processing of most common materials. These materials include dissimilar materials welding, photoablation of ceramics and polymers using the excimer laser, and high-pressure laser cutting. Expert's company has all current types of industrial lasers: YAG, excimer,and ultrafast.

Expert and his associates have experience with processing small features on polyimides, PTFE, and paralene coatings. They have achieved holes as small as 0.001 inches in diameter and can control material removal depth to the submicron range.

In dross-free high pressure cutting, he has successfully cut metals and non-metals at speeds of up to 500 inches per minute (depending on thickness and the thermal properties of the material.) Spectralytics has achieved accuracies of +/- 0.5 microns. They specialize in cutting medical stents.


Expert and his associates assemble components in a vacuum chamber and guide a laser beam through a window. They achieve hermetic weld-seals equivalent to the vacuum inside the chamber. In the microwelding area, Expert's group has successfully buttwelded wire as small as 0.003 inches and tubing as small as 0.010 inches in diameter.

Expert and his associates have mastered precise, fast laser drilling with aspect ratios (hole depth to hole diameter) up to 50:1. With most engineering materials they experience negligible hole tapers and heat-effect zones.

Expert has a wide background in designing new products and manufacturing processes, primarily in the area of precision mechanical components and assemblies for the computer and aerospace markets, specifically including magnetic recording suspension and actuator assemblies. He has been responsible for getting several products into high volume production, and managing complex projects in high-growth companies.

Expert has developed a process to weld plates of titanium, hastelloy, nickel, and stainless steel. The process involves several feet of laser weld using pressure and shielding gas at the fusion site. This process allows the plates to be made with 10-20 percent of conventional tooling and cycle times.

Expert has developed laser based processes for flex circuits,pacing leads,embolic protecters and cutting catheters

Expert may consult nationally and internationally, and is also local to the following cities: Minneapolis, Minnesota - Saint Paul, Minnesota - Burnsville, Minnesota - Saint Cloud, Minnesota - Eden Prairie, Minnesota - Minnetonka, Minnesota
