“…The absorption band near 490 nm consists of transitions from the Stark levels of the ground state to the 3P0 level when at shorter wavelengths the absorption to the 116, 3P1, and 3Ρ2 dominates. The cross-section values determined here are in reasonable agreement with reported literature data for Ρr3+ doped YLF [11,31], YAP [30], and ZBLAN [34].…”

“…Praseodymium ion has been demonstrated to lase in the 480-520 nm, bluegreen region in various fluoride and oxide crystals, such as LiYF 4 :Pr3+ (YLF:Pr3 +) [10,11], GdLiF4 :Pr3+ [12], Y3Al5 O 12 :Pr3+ (YAG:Pr3+) [13,14], YAlO3:Ρr 3 + (YΑΡ:Pr3+) [14] and Gd 3 Ga5 O 12 :Pr3+ (GGG:Ρr3+) [14] under one photon pumping. Recently, Pr3+ activated fluoride fibers have been demonstrated to oscillate at short wavelengths under different upconversion excitation conditions [15][16][17][18].…”

Emission and absorption spectra, lifetimes, and branching ratios in the blue spectral region have been experimentally determined for numerous oxide, fluoride and phosphate materials doped with Pr 3+ ions. The emission cross-sections have been evaluated using the principle of reciprocity. Α theoretical model allowing a prediction of the blue lasing characteristics of the praseodymium activated waveguide structures has been developed and employed to the investigated materials.

“…A high laser threshold was also observed in Nd:KYF 4 , which limits the use of KYF 4 as a rare earth doped host crystal. Sandrock et al [20] further confirmed the weak and undesirable thermo-optical properties of Pr:KYF 4 . By using an argon-ion laser as pump source, they obtained the first red laser emission at 642.5 nm.…”

The pump source is an especially developed, compact, slightly tunable and intra-cavity frequency-doubled diode-pumped Nd:YAG laser delivering a CW output power up to about 1.4 W around 469.1 nm. At this pump wavelength, red and orange laser emissions are obtained at about 642.3 and 605.5 nm, with maximum output powers of 11.3 and 1 mW and associated slope efficiencies of 9.3% and 3.4%, with respect to absorbed pump powers, respectively. For comparison, the Pr:KYF 4 crystal is also pumped by a InGaN blue laser diode operating around 444 nm. In this case, the same red and orange lasers are obtained, but with maximum output powers of 7.8 and 2 mW and the associated slope efficiencies of 7 and 5.8%, respectively. Wavelength tuning for the two lasers is demonstrated by slightly tilting the crystal. Orange laser operation and laser wavelength tuning are reported for the first time.

“…Furthermore, lasing operation in several Pr 3? -doped materials such as LiYF 4 (Sandrock et al 1994;Richter et al 2006;Hashimoto and Kannari 2007a), BaY 2 F 8 (Richter et al 2006), Y 3 Al 5 O 12 Kannari 2007b), YAlO 3 (Danger et al 1994) have already been reported.…”

In order to reach the efficient performance of Pr 3? doped fiber lasers, we present a numerical model for continuous wave operation of a Pr 3? : ZBLAN, and study the influence of the fiber length and Pr 3? concentration on the pump power, optimum reflectivity of FBG 2, optimum fiber length, threshold and slope efficiency at 638 nm. The shooting technique is applied to estimate the initial conditions and finite difference method is used for solving the rate and propagation equations. The flowchart for calculating the numerical solutions is presented. In this work we analyze and optimize the laser parameters in details which is crucial to experimental design.
