Stimulated Raman scattering of nanosecond pulses in a KGd(WO₄)₂crystal

Hydrothermal synthesis and luminescence behavior of rare-earth-doped NaLa(WO4)2 powders

“…In this paper, a simple hydrothermal route to synthesis rare-earth-doped luminescent NaLa(WO 4 3+ , and Er 3+ ) in 90 mL deionized water with the total metal cations being 3.6 mmol. The solution was then adjusted to the desired pH 6.0 with NaOH and stirred for 10 min at room temperature.…”

“…Their structural diversity provides these crystals with numerous physical properties. In addition to the well-known laser potential [2,3], it is also possible to take benefit of the nonlinearities of the host as efficient Stokes converters of laser radiation [4][5][6][7][8][9]. These compounds have been prepared by several different processes such as the flux growth [10,11], solid-state reaction [12], and hydrothermal reaction over an extensive period [13].…”

Intracavity Raman laser generating a third stokes component at 1.5 μm

“…It yields high power pulsed radiation at low pump energy levels. At the same time the Nd:KGW crystal is an effective SRS-active medium [11,12] with a rich phonon mode spectrum [13]. When the 901.5 cm -1 Raman line of the Nd:KGW crystal is used, this laser source can generate eye-safe radiation at a new wavelength of 1.5 μm.…”
