High Performance
30 Watt CO2 Laser
for Thin Film Cutting
The Synrad vi30+ is designed, engineered, and built for Original Equipment
Manufacturers (OEMs) seeking a reliable, compact 30 Watt CO2 laser source.
Outstanding power stability and beam quality ensures clean, crisp results while a new,upgraded RF module improves reliability.

Overview
For more than 20 years, Synrad 30 Watt CO2 lasers have been one of the most widely chosen CO2
laser sources among OEMs and System Integrators worldwide. Used primarily as a laser source formarking and coding applications, the highly stable output power and beam quality has found its
way into thin film cutting applications.
Thin Film Application/Process

CO2 Laser Requirement

Through cutting, selective depth cutting,scoring, and perforating~30 Watts average power

Stable power output, high beam quality, and fastrise/fall times to minimize heat affected zone

The Effects of Power Stability on Cutting Thin Films
Poor cut quality leads to higher levels of waste and lost productivity, increasing production costs
and lowering profitability. The images below demonstrate the effects of power stability on cutting
thin films. Poor power stability causes fluctuations in the laser power, yielding inconsistent results.

The yellow arrows indicate areas
where the cuts did not penetrate
through the thin film.

In this example the center cutgoes completely through the thinfilm, while the other cuts did not
penetrate through.

Avoiding Common CO2 Laser Selection Pitfalls
To avoid poor power stability:• Ask for a power stability specification that includes measurements from cold start. Some laser
vendors only report power stability after a significant warm-up time.

• Look at the formula used to calculate power stability. The variation in power should be scaled by
the sum of the minimum and maximum power measured. Some vendors scale the variation
by 2x the maximum power, making the stability appear better than you would measure on yoursystem.

• Request information on power stability at the power level needed to process your material.
Some vendors ship lasers with power stability worse than 50% at low duty cycles.
To avoid poor and/or unstable beam quality:• Ask about thermal gradients in the laser design. Strong thermal gradients cause instability that
may cause the beam profile and/or power to fluctuate over time. Some vendors have lasers
where the divergence can vary as much as 22%, which will cause a significant change in spot
size and process quality.
