“…The experimental setup of the compact free-running Er,Yb:glass laser is shown in figure 3. The laser rod (diameter: 1 mm, length: 5 mm) was prepared from the commercial phosphate glass (LGS-DE synthesized at the Institute of Radio Engineering and Electronics, Russian Academy of Sciences [19], see table 2) doped with the Er 3+ and Yb 3+ ions with a concentration of 0.5 × 10 20 cm −3 and 25 × 10 20 cm −3 , respectively. The rod was placed into a ZrO 2 highly efficient diffuse reflector to ensure uniform pump distribution.…”

We report on the development of a compact diode-end-pumped eye-safe (~1.54 µm) passivelycooled Er,Yb:glass laser. The design of this laser is facilitated by the use of a double-pass pumping scheme and a special ZrO 2 diffuse reflector for a uniform pump distribution. In the free-running mode, this laser generates 8.2 mJ/3 ms pulses with a slope efficiency of 15%. Passive Q-switching is provided by saturable absorbers made of transparent glass-ceramics containing Co 2+ :γ-Ga 2 O 3 or Co 2+ :MgAl 2 O 4 nanocrystals with a spinel structure. In the latter case, 0.7 mJ/10.5 ns pulses are generated corresponding to >60 kW peak power and good beam quality (M 2 = 1.4). The designed laser is suitable for portable range-finders.

“…10 One glass was doped only with ytterbium and erbium ions (Yb-Er glass), and the second was also doped with chromium ions (Cr-Yb-Er glass). The Yb 3 and Er 3 concentrations were identical in the two glasses: N Yb 2.1 × 10 21 cm −3 and N Er 1.3 × 10 19 cm −3 .…”
