New Crystalline Laser Generates 1 Watt at an Eye-Safe 1.5 μm

Er,Yb:YAl3(BO3)4 laser is several times more powerful than previous lasers.

Breck Hitz

Because the human cornea does not transmit wavelengths longer than 1.5 μm, lasers in this spectral region are less dangerous than shorter-wavelength lasers and thus are designated “eyesafe.” Such lasers are desirable in any application where there is a possibility that the beam could encounter human eyeballs; for example, aerial navigation, free-space telecommunications, environmental sensing and medicine. The rare-earth element erbium has a good laser transition at 1.5 μm but is a poor absorber at the ∼1-μm wavelength of common pump diodes. For that reason, most eye-safe...Read full article
