Continuous-wave Tm:YLF laser with ultrabroad tuning (1772-2145 nm)
Demirbaş, Ümit; Thesinga, Jelto; Beyatlı, Ersen; Kellert, Martin; Pergament, Mikhail; Kärtner, Franz X. (Optica Publishing Group, 2022)We report detailed experimental data aiming for rigorous investigation of Tm:YLF laser performance, especially with a focus on tuning behavior. Continuous-wave (cw) lasing performance of Tm:YLF crystals with thulium dopings ... -
Efficient Tm:YAG and Tm:LuAG lasers pumped by 681 nm tapered diodes
Beyatlı, Ersen; Sumpf, Bernd; Erbert, Götz; Demirbaş, Ümit (OSA - The Optical Society, 2019)In this paper, we present highly efficient continuous-wave (cw) laser operation of Tm:YAG and Tm:LuAG lasers pumped by high-brightness red tapered diodes. The single-emitter tapered diode lasers (TDLs) provide up to 1 W ... -
The electrochemical and spectroelectrochemical properties of metal free and metallophthalocyanines containing triazole/piperazine units
Demirbaş, Ümit; Akyüz, Duygu; Mermer, Arif; Akçay, Hakkı Türker; Demirbaş, Neslihan; Koca, Atıf; Kantekin, Halit (Pergamon-Elsevier Science Ltd, 2016)The synthesis and characterization of novel peripherally tetra [1,2,4]-triazole substituted metal-free phthalocyanine and its metal complexes (Zn(II), Ni(II), Pb(II), Cu(II) and Fe(II)) and the investigation of electrochemical ... -
Widely unable dual-wavelength operation of Tm:YLF, Tm:LuAG, and Tm:YAG lasers using off-surface optic axis birefringent filters
Beyatlı, Ersen; Demirbaş, Ümit (Optical Soc Amer, 2018)In this work, we have demonstrated dual-wavelength continuous-wave laser operation in diode-end-pumped Tm:YLF, Tm:LuAG, and Tm:YAG lasers. A 3-mm-thick quartz birefringent filter with an optical axis 45 degrees to the ...
