Diode-pumped room temperature single longitudinal mode lasing of Tm,Ho:YLF microchip laser at 2050.5 μm

The Role of Axions in the Formation of the Photoluminescence Spectrum in Dispersive Media

“…A few words about silicon, the main material of electronics: The review [36,55,58] discussed the problem of mirror symmetry of PL and absorption of multi-dimensional silicon nanoparticles suspended in ethanol. The contribution of the anti-Stokes component in the PL spectrum is noted.…”

“…here ν < ν pl . The Equations ( 7) and ( 8) helped to author to understand the PL spectra, obtained by him [34][35][36], or borrowed from the materials of various authors, in which the results on PL are presented, and to which we will return below. Unfortunately, the accuracy of the frequency estimation at the stage of analysis of the PL spectrograms, published in the journals in the DM could not be high enough.…”

“…At the output of the DM, we get, as a rule, an expanded spectrum of PL. For example, when silicon nanoparticles placed in ethanol [36,58,59] are excited by argon laser radiation, a PL spectrum with a width from 464 nm to 670 nm is obtained.…”

A high efficiency Ho:YAlO3 laser pumped by Tm:YLF laser with a Volume Bragg Grating

“…One way to alleviate these effects is to make Ho and Tm in separate crystals. With the quickly development of high power 1.9 µm laser as an efficient pump source [14][15][16], the 2 µm lasers based on Ho doped crystals have become prominent in these applications, and the host materials for these Ho lasers are usually Y 3 Al 5 O 12 (YAG), LiYF 4 (YLF). The output wavelength of Ho:YAG laser is centered at 2.09 µm, and the output wavelength of Ho:YLF laser was centered at 2.05 µm [17].…”

A tunable single-frequency green laser based on a wedged Nd:YVO4 crystal and a KTP crystal

“…Furthermore, the processing cost of etalons is expensive, and two to three etalons are sometimes needed to obtain single frequency operation. In addition, other methods with a microchip laser [5], a nonplanar ring laser [6] and a twist-mode-cavity-laser [7] to obtain a single-frequency laser are not applicable for intra-cavity frequency doubling.…”
