Molybdenum disulfide (MoS2) – based, tunable passively Q switched thulium-fluoride fiber (TFF) laser
The generation of spatial rogue waves, or “hot spots,” is demonstrated experimentally in the passively Q -switched Nd:YAG laser system operating a low-power regime well below self-focusing limit. Here, we report dependence wave statistics on number transverse modes that interact cavity. Our o...
Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...
We report an efficient, visible, nanosecond optical parametric generator of periodically poled lithium niobate pumped at 532 nm by a frequency-doubled, diode-pumped, passively Q -switched, single-mode Nd:YAG laser with 90-muJ pulse energy. The signal radiation is tunable from 637 to 593 nm. The maximum signal-conversion efficiency is 23%. Optical parametric amplification of a He-Ne laser at 632...
