Continuous wave laser operation in Nd:GGG depressed tubular cladding waveguides produced by inscription of femtosecond laser pulses Liu, Hongliang Jia, Yuechen Chen, Feng Vázquez de Aldana, Javier R. Waveguides Femtosecond lasers Integrated optics Waveguide lasers 2209.10 Láseres 2209.13 Óptica no lineal Depressed tubular cladding waveguides have been produced in Nd:GGG crystals by using multiple inscription with femtosecond (fs) laser pulses. The guiding cores are located inside the tubular regions with crosssection diameters of 90-150 μm, which are surrounded by fs-laser induced low-refractive-index tracks. At room temperature continuous wave (cw) laser oscillations at wavelength of ~1063 nm have been realized through the optical pump at 808 nm. The slope efficiency of the cladding waveguide lasers is as high as 44.4% and the maximum output power at 1063 nm is 209 mW, which shows superior laser performance to the Type II stress induced Nd:GGG waveguides. 2014-06-26T07:44:27Z 2014-06-26T07:44:27Z 2013-01-18 info:eu-repo/semantics/article Optical Materials Express 3 (2), 278-283 2159-3930 http://hdl.handle.net/10366/123366 eng info:eu-repo/semantics/openAccess application/pdf Optical Society of America https://gredos.usal.es/bitstream/10366/123366/5/OptMatExpress_3_278_2013-NdGGG-Cladding.pdf.jpg Hispana TEXT http://rightsstatements.org/vocab/CNE/1.0/ Gredos.
