A new chromium ytterbium erbium laser glass LGS-Kh was used for the first time in minilasers emitting at 1.54 μm and characterized by a very low (less than 5 J) threshold and a relatively high (up to… Continue Reading
The prototype of a passively Q-switched, longitudinally diode-pumped erbium glass laser is fabricated. A slope efficiency of 38% is achieved in the free-running lasing regime. It is shown that a pump… Continue Reading
This paper proposes a method for improving the quality of the pulse generated by an erbium laser by means of a slit stop formed in the active element. It presents results obtained for a radiator with… Continue Reading
Perspectives to develop a new line of compact simple-to-use reliable and low-cost high- power laser devices on the base of activated glass fibers will discuss. They may find wide applications in… Continue Reading
The influence of cerium oxide on photo- and gamma-stability of chromium-ytterbium-erbium phosphate glasses is studied. It is found that UV irradiation does not cause any noticeable changes in the… Continue Reading
The lasing parameters of active elements made of a new LGS-KhCh chromium — ytterbium — erbium glass are studied in the free-running mode. The methods for optimising the pump parameters and the laser… Continue Reading
An investigation was made of several relationships governing excitation transfer in Cr-Yb-Er phosphate glasses. The activator concentrations were optimized. A family of the new erbium-doped laser… Continue Reading
Continuous wave lasing is obtained for the first time in a flashlamp-pumped ytterbium ? erbium-doped glass.
