Er3+, Yb3+ co-doped phosphate
glass is a well-known and commonly used active medium for lasers emitting in
the “eye-safe” spectral range of 1,5-1,6 µm.
As an eye-safe wavelength laser, 1540um
,Er3+/Yb3+ co-doped phosphate glass lasers have attracted much attention
for their compactness and low cost, such as laser generation and signal
amplification because the wavelength of 1540nm is just at the position of
the eye-safe and the fiber optic communication window. 1540nm lasers have
used in ranging finder, radar, target recognition. Er3+/Yb3+ co-doped
phosphate glass cooperate with passive Q-Switch crystal cospinel can get 1540nm
pulse solid-state laser.
