WebWe review recent achievements with ultrafast bulk lasers and amplifiers based on Yb:YAG and Yb:glass. Special attention is paid to those aspects of the quasi-three-level nature of these gain media that are important for short-pulse generation. The potential of Yb-doped media for efficient short-pulse generation and amplification is compared to ... WebDivisor de feix.

WebWe demonstrate a power-scalable concept for high-power all-solid-state femtosecond lasers, based on passive mode locking of Yb:YAG thin disk lasers with semiconductor saturable-absorber mirrors. We obtained 16.2 W of average output power in pulses with 730-fs duration, 0.47-µJ pulse energy, and 560-kW peak power. This is to our knowledge the … WebThe beam parameter product (BPP) is another metric used to evaluate the quality of a laser beam.

WebCompared to soda-lime glass, borosilicate glass exhibits significantly increased scratch and abrasion resistance. The high thermal resistance allows this material to withstand extreme and fluctuating temperatures. At the same time, its high transmission and optical clarity provide excellent visual quality. WebWe propose and theoretically analyze three-level cladding-pumped fiber lasers in which the laser-active dopant is placed in a ring around a single-mode core. A ring-doped laser can work efficiently at wavelengths with strong small-signal absorption. This is otherwise difficult in a cladding-pumped fiber. Moreover, ring doping makes the laser less sensitive to …
