| Solid state lasers are often based on paramagnetic ions that are imbedded in a crystal host. Recently work has focused on utilizing transition metal ions, particularly chromium, to create a laser capable of emitting light in the middle infrared wavelengths. We investigated crystals of chromium doped CdGa2S4 with X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDXS), electron paramagnetic resonance (EPR), optically induced EPR, absorption and photoluminescence (PL) measurements to characterize the crystals. |
