Lasers

Lasers: Exciting!

Also, dangerous.

Only safety-conscious adults with proper safeguards should operate lasers of any kind.

CO₂ Lasers

Hyrel offers a 40w CO₂ laser on some of our Hydra models.

We recommend at least 500 cfm (850 m³/h) of exhaust while lasering.

Hyrel Specific

Settings

Your acutal laser controller, on the Aux Heads tab, should be set to "Laser_40".
Your safety/mirror/lens controller, on the Heads 1-5 tab, should be set to "CO2_Laser" or the newer "CO2_Lens".

Z-zero should be set 8 mm from the bottom of the focusing lens hardware for the CO2 laser.

Informational Videos

Below are links to some VERY helpful videos from a gentleman named Russ, who purchased a laser engraver very similar to ours. In these videos, he shares his experiences, advice, and safety tips. While some of what Russ explains does not apply to using lasers on Hyrel equipment, much of it does. Please watch all these videos, even if you don't feel you need the information. Safety first!

Diode Lasers

While less powerful than CO₂ lasers, diode lasers are still dangerous, and the same safety precautions apply.

Diode Laser Properties

Property	LA5-808	LA6-450
Watts	~5	~6
Wavelength	808	450
Columnated	FAC	No

Z-zero should be set 18 mm from the bottom of the focusing lens hardware for the Diode lasers.

Hyrel offers diode lasers in several configurations:

• The LA6-450, a 6 watt, 450 nanometer laser. LA6-450 Intro Video
• The LA5-808, a 5 watt, 808 nanometer laser. LA5-808 Intro Video
• The LA3-450, a 3 watt, 450 nanometer laser.
