چکیده

High-quality monoclinic planar waveguide crystals of Tm-doped KY(WO4)2 codoped with Gd3+ and Lu3+ were grown by liquid-phase epitaxy. For the first time, planar waveguide lasing was demonstrated in a monolithic cavity in the 2 µm spectral range. The laser was operated in the Q-switched mode using a Cr2+:ZnSe crystal as saturable absorber and in the continuous-wave regimes. The Q-switched planar waveguide laser delivered pulse energies up to 120 nJ at a repetition rate of 7 kHz.

Yb-doped KY(WO4)2 planar waveguide laser.

High-quality monoclinic KY(WO4)2 optical waveguides were grown by liquid-phase epitaxy, and laser operation of an Yb-doped KY(WO4)2 waveguide was demonstrated for the first time to our knowledge. Continuous-wave laser emission near 1 microm was achieved with both surface and buried planar waveguides. An output power of 290 mW was obtained in the fundamental mode and the slope efficiency was abo...

A 35 : Impurity - doped Micro - lasers

Rare-earth-ion-doped monoclinic potassium double tungstates KY(WO4)2, KGd(WO4)2, and KLu(WO4)2 are excellent host materials for solid-state lasers [1]. High-quality KY(WO4)2 optical waveguides were grown and laser operation was demonstrated for the first time [2]. Co-doping a KY(WO4)2 layer with Gd 3+ and Lu 3+ ions allows for lattice-matched layers with increased refractive index contrast with...

Continuous-wave and Q-switched operation of a compact, diode-pumped Yb3+:KY(WO4)2 planar waveguide laser.

A diode-pumped LPE-grown Yb:KYW planar waveguide laser is demonstrated in a microchip monolithic cavity configuration. Output powers as high as 148 mW and thresholds as low as 40 mW were demonstrated during continuous-wave operation. Pulses of 170 ns duration with maximum pulse energy of 44 nJ at a 722 kHz repetition rate were generated when Q-switched using a semiconductor saturable absorber m...

On-chip Integrated Amplifiers and Lasers Utilizing Rare-earth-ion Activation

This contribution reviews our recent results on rare-earth-ion-doped integrated amplifiers and lasers. We have concentrated our efforts on complex-doped polymers [1], amorphous Al2O3 [2], and crystalline potassium double tungstates [3]. A polymer host material, based on a cycloaliphatic diepoxy cured with a fluorinated dianhydride, has been developed [4]. When activated with the rare-earth-ion-...
