Abstract
Lasers of different classes based on the stimulated Raman scattering (SRS) effect in waveguide elements from tellurite glasses with a power from tens of microwatts to tens of watts are theoretically studied. Due to high SRS gain and large SRS frequency shift, tellurite glasses are promising materials for the development of laser sources at a wavelength of nearly 2.3 \(\mu\)m under pumping at a wavelength of nearly 2 \(\mu\)m. The detailed numerical modeling of SRS lasers based on special single-core and multicore tellurite fibers is performed. It is shown that, at optimal parameters, the efficiency of pumping power conversion into SRS wave power may exceed 50%. The detailed modeling of low-power lasers based on high-Q microresonators is carried out to find optimal parameters and generation limiting factors.
