Optical spectroscopy of the RbPb_2Cl_5:Dy^3+ laser crystal and oscillation at 55 μm at room temperature

Mid-IR radiation generated by Dy:PbGa2S4 laser

“…the same value as was reached for Dy:RbPb 2 Cl 5 in [6]. The dependence of 5.5 µm output Dy:PGS oscillation pulse energy on the absorbed pumping energy is presented in Fig.…”

“…There is a growing body of studies focused on the search, development and spectroscopic investigations of new rare-earth doped and non-hygroscopic low phonon energy halide single crystals that could potentially be used as solid-state optical amplifiers in middle infrared (MIR) laser cavities [1][2][3][4][5][6][7][8]. Cs 4 PbBr 6 is a long-time known bromide [9] that, among several alkalibased lead bromides, has been investigated in the form of bulk crystals and thin films for its particular optical properties arising from the 6s 2 Pb 2+ cations electronic outer shell [10,11].…”

Ultrashort pulse generation in the mid-IR

“…2): mid-IR sources have great potential for extreme applications such as high order 50 harmonic generation and attosecond pulse generation. Ultrashort pulses in the mid-IR permit scrutinizing atomic and molecular dynamics [2, 3,4], they allow imaging molecular structure [5], and they enable scaling of coherent soft X-ray generation beyond the keV on a tabletop [6]. In medicine, mid-IR lasers permit localized cutting and tissue removal due to the strong absorption of tissue at 55 6.45 µm [7].…”
