Erbium Doped Phosphate Glasses For Lamp Pump
Erbium-doped phosphate glass is an attractive host material for rare earth amplifiers and lasers. It generally has a large stimulated emission cross-section and high quantum efficiency. The doping of erbium ions is much higher than that of quartz glass, so the gain per unit length is high. It is especially suitable for making continuous operation and short length devices. Amplifiers made with erbium-doped phosphate fibers can achieve tens of decibels of amplification within a few centimeters.
◇ Large stimulated emission cross section
◇ Large output light power
◇ High gain
◇ Cr14: Erbium phosphate glass for xenon lamp pumping laser device and laser range-finder
◇ CrE5: CrE5 is for large energy output application. The glass rod of CrE5 can work safely at 1Hz repetition offer surface strengthen treatment at over 10J output level.
