The crystal advancement, absorption spectra, J-O parameters, emission spectra, fluorescence lifetimes plus the energy transfer mechanism in Yb, Ho, Pr: LuAG crystal have been analyzed In this particular get the job done. The Electricity changeover efficiency from the decrease laser amount of Ho³�? ⁵I7 to Pr³�? ³F2 level is as higher as sixty six.6%, indicating that the Pr³�?ion is an efficient deactivation ion for Ho³�?ion in Lu3Al5O12 crystal. These success exhibit that Yb, Ho, Pr: LuAG crystal may perhaps turn into a promising content for building solid state lasers at all-around three μm below a traditional 970 nm LD pump.

A two order of enhancement in close to-infrared emission from Nd3+ in Ce3+/Nd3+ codoped yttrium aluminum garnet (YAG) matrix is attained. This is because of successful absorption with the allowed 4f-5d changeover of Ce3+ ions then transfer to Nd3+ ions by way of a effectively matched Vitality level. This is among the most economical in close proximity to-infrared emission from Nd3+ ions strongly sensitized by fascinating having an permitted changeover in an inorganic matrix.

By learning quasi-ongoing wave (QCW) operation of the Ce:Nd:YAG sound-state laser right pumped by LED arrays, we demonstrate the feasibility of immediate-LED pumping as an alternative to immediate-diode or flashlamp pumping. LEDs emitting both at 460 or 810 nm ended up utilized to pump an uncooled Ce:Nd:YAG laser rod (at 30-Hz repetition level for tens of seconds).
