چکیده
We present a bi-directionally 793-nm diode-pumped Tm 3+ , Ho -codoped silica polarization maintaining double-clad all-fiber laser based on single-oscillator architecture emitting 195 W at 2.09 µm in continuous wave mode of operation, with beam quality near the diffraction limit (M 2 = 1.08). The power scaling is only pump-power-limited range total available pump (540 W).

متن کاملMonolithic Nd:YAG fiber laser.
A single-crystal Nd:YAG fiber with polished and coated endfaces has been operated as a monolithic, guided-wave laser oscillator. The 47-microm-diameter, 7-mm-length fiber oscillator operated with a threshold of 3.7 mW and a slope efficiency of 10.5%. Seventy-five percent of the laser power was in the fundamental spatial mode.

We build up a LD end-pumped Er,Yb:YAB laser at 1.55 μm and improve the laser performance by end cooling the gain medium efficiently through a sapphire plate. 680 mW cw single transverse mode laser output was obtained with the slope efficiency of 16.3%. Using an etalon placed in the laser cavity, 400 mW cw single frequency 1.55 μm laser output was achieved with the slope efficiency of 11.8%. The...
متن کاملHighly efficient, diffraction-limited laser emission from a vertical external-cavity surface-emitting organic laser.
We report on a solid-state laser structure functioning as the organic counterpart of a vertical external-cavity surface-emitting laser (VECSEL) design. The gain medium is a poly(methyl methacrylate) film doped with Rhodamine 640, spin casted onto the high-reflectivity mirror of a plano-concave resonator. Upon pumping by 7 ns pulses at 532 nm, a diffraction-limited beam (M(2)=1) was obtained, wi...
متن کامل250 W single-crystal fiber Yb:YAG laser.
We demonstrate an Yb:YAG single-crystal fiber laser with 251 W output power in continuous-wave and an optical efficiency of 44%. This performance can be explained by the high overlap between pump and signal beams brought by the pump guiding and by the good thermal management provided by the single-crystal fiber geometry. The oscillator performance with a reflectivity of the output coupler as lo...
