“…In this work, results of the material preparation and near-IR spectroscopy of Pr 3+ doped PbCl 2 are presented. The binary compound PbCl 2 has a low moisture sensitivity and a narrow phonon spectrum ( max ω h 180cm -1 ), which enables efficient emission in the infrared (IR) spectral region [8][9][10]. Results of temperature dependent absorption and emissions studies in the 1.6 μm IR region will be presented and used to determine transition crosssections and effective gain cross-section spectra.…”

The 1.6 µm emission properties originating from the 3 F 3 , 3 F 4 → 3 H 4 transition of Pr 3+ ions in Pr-doped PbCl 2 crystals were investigated for possible application in resonantly-pumped, eye-safe laser development. Pr: PbCl 2 was synthesized and purified through a combination of zone-refinement and chlorination of the melt before growing crystals by Bridgman technique. Under optical pumping using a ~1.48 μm laser diode, an IR emission band centered at ~1.65 μm with a full width at half maximum of 75 nm was observed at room temperature. The decay transient of the thermally coupled 3 F 3 and 3 F 4 excited states was single exponential with a value of 170 µs at room temperature. The lifetime increased to 350 μs at 77 K suggesting the existence of some non-radiative decay through multi-phonon relaxation. Emission cross-section spectra were determined using the principle of reciprocity and Ladenburg-Fuchtbauer method and yielded peak values of 3.8x10 -20 cm 2 and 5.7x10 -20 cm 2 at room-temperature and 77 K, respectively. The effective gain cross-section spectra of Pr: PbCl 2 will be discussed for possible lasing in the 1.6-1.7 μm region.

“…It is now widely established that crystal growth by the Bridgman method must be carried out in sealed silica ampoules under a low pressure (~10 -2 atm) of Cl 2 or HCl (HBr for bromides) gas to avoid bubble formation, and at low growth rates (~0.1-1 mm.h -1 ) in axial thermal gradients typically 15-20 K.cm -1 with opening angles of the ampoule bottom lower than 120° to avoid shear stress induced cracks. PbX 2 (X=Cl,Br) starting materials must be purified by previous solidification runs by the Bridgman method [Basiev et al, 2004]. In KPb 2 Cl 5 crystals, roundtrip losses mechanisms, such as laser beam depolarization and double refraction [Condon et al, 2006b] reaches 1 %.…”
