| 11. | Industrial applications of erbium boride include use in semiconductors, the nozzles of rocket engines.
|
| 12. | An Erbium laser is more superficial.
|
| 13. | This permitted the discovery of four new elements : Yttrium, Terbium, Erbium and Ytterbium.
|
| 14. | Erbium and CO 2 fractional systems have a better safety profile than lasers of the past.
|
| 15. | It has four fiber strands, using Erbium-doped fiber amplifier repeaters and wavelength division multiplexing.
|
| 16. | The characteristic of both Erbium and CO2 laser wavelengths is that they are highly absorbed within water.
|
| 17. | It's the root of four element names, Yttrium, Erbium, Ytterbium, and Terbium.
|
| 18. | Erbium is ferromagnetic below 19 K, antiferromagnetic between 19 and 80 K and paramagnetic above 80 K.
|
| 19. | Pump lasers, coupled to the optical amplifiers, activate the erbium, which energizes the light pulses.
|
| 20. | CO 2 resurfacing has been shown to have an increased risk of hypopigmentation and scarring than erbium lasers.
