Career starting point

Coherent Medical in Palo Alto launched my engineering career and established an early foundation in lasers, optics, thermal hardware, precision assembly, and medical equipment.

Systems and components

Assembled cabinet-scale CO₂ surgical-laser hardware and optical delivery components.
Worked on ophthalmic photocoagulation equipment integrated with a Zeiss slit-lamp assembly.
Built attenuators, heat sinks, mounts, and production sub-assemblies.
Supported precision optical and mechanical assembly in Coherent Medical's newer Palo Alto facility near Highway 101.

Recognized assembly improvement

Created a compact half-moon bearing-loading fixture from formed material, wire, and heat-shrink.
Held rows of small ball bearings in alignment during assembly of the Zeiss mechanism.
Made a difficult precision-assembly operation faster and more repeatable.
Received internal recognition for the improvement at approximately age 20.

The hero is an original representative reconstruction using the Coherent 450 cabinet-laser family as historical context. It is not an archival photograph or a claim that this exact unit was assembled by Evan. Coherent's current ophthalmic applications page supplies present-day application context.

Ophthalmic systems

Contributed to photocoagulation equipment combining laser hardware with a precision Zeiss clinical viewing assembly.

Production problem solving

Created a simple fixture that improved repeatability in a difficult bearing-installation operation.

Broad hardware experience

Worked across optical, thermal, mechanical, enclosure, and assembly elements rather than one isolated component.
