Iradion Eternity Series- 30/40 Watt
The Iradion Eternity (model E-30 and E-40) is a 30/40 Watt CO2 laser tube and is based on Iradion’s proven Ceramic Core Technology. One of the primary differences and technological advancements that is incorporated in this design is the resonator. Latest release is model E-25 with 25 Watt and 9.3 µm wavelength.
The E-30’s/E-40’s resonator is a Z-folded (2-fold) unstable resonator. This allows for a smaller package design when compared with other 30/40 Watt laser tubes and is the shortest (folded) resonator in the 30 – 50 watt CO2 laser class, but has a remarkably long (unfolded) resonator length, resulting in high stability.
This provides superior power and beam diameter stability. Early test have shown the from-cold power stability in the ±2% range.
