Er,Yb: Glass laser glass for eye-safe laser of 1540nm or 1.5µm to 1.6µm

Erbium ytterbium Co doped phosphate glass has a wide application prospect because of its excellent properties. Generally, it is the best glass material for 1.54um laser due to its visual safety wavelength of 1540nm and high transmittance through the atmosphere. It also applies to medical applications where the need for eye protection may be difficult to manage or reduce or hinder basic visual observation. In recent years, it has replaced EDFA for optical fiber communication with its superior performance. Great progress has been made in this regard.

Er3+ emission transition occurs within this wavelength range corresponding to the 4I13/2 →4I15/2 . However, Er3+absorption itself is too weak to allow direct pumping and so, energy transfers are required. The most efficient ones are given by Yb3+ ions under absorption from the 2F7/2 → 2F5/2 transition, followed by energy transfer to the 4I11/2 Er3+ level and fast nonradiative transition to the Er3+  4I13/2 level which emits the expected fluorescence.Er,Yb:glass laser with radiation output at the wavelength of 1540 nm does not require the addition of additional components.

Er3+/Yb3+ co-doped phosphate glass — as the 1540nm eye-safe radiation sources pumped by LD which can emit eye-safe 1540nm laser radiation directly used in laser ranging finder and telecommunication communication

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 -co:spinel to get 1540nm pulse solid-state laser.

Co spinel——saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe wavelength of 1.5 μm

Lasers emitting at 1.5µm are of great interest for several industrial applications. This interest is, first of all, due to eye-safety of 1.5-µm radiation. Other advantages of this wavelength are high transparency in atmosphere and fused-silica wave guides and availability of sensitive room temperature light detectors(Ge and InGaAs photo diodes).All this makes 1.5µm lasers very attractive for applications in range-finder, environmental sensing, telecommunications, surgery,etc. Co：Spinel absorption peak is close to 1520nm,which is most used in eye-safe laser. The absorption cross-section at 1520nm is 3.5×10-19cm2 and at 1331 is 2.8×10-19cm2,it has reported as Q-switch crystal for Er,Yb Glass and Nd:GYSGG,Nd:YALO3.
