From a Cr(4+):forsterite crystal with a differential absorption coefficient of 0.57 cm(-1), as much as 900 mW of cw output power has been obtained at 1.26 mum and at a crystal boundary temperature of 15 degrees C with an absorbed pump power of only 4.5 W at 1.06 mum. No chopping of the pump beam was necessary. An efficient radiative cooling technique was further employed to cool the laser and no subsequent power fading was observed. To the author's knowledge, the measured absorbed power slope efficiency of 29.5% represents the highest cw power performance reported to date from a Cr(4+):forsterite laser pumped by a Nd:YAG laser around room temperature. The role of the low differential absorption coefficient in the reduction of thermal loading is further elucidated by presenting comparative cw power performance data with a second Cr(4+):forsterite crystal having a differential absorption coefficient of 1.78 cm(-1) in the temperature range between 12 and 35 degrees C. Finally, some interesting multipulse effects of the laser observed in the millisecond regime during quasi-cw operation at 50% duty cycle are described.Publication Metadata only Infrared parametric fluorescence in segmented KTP channel waveguides(Optica Publishing Group, 1998) Aschieri Pierre; Baldi, Pascal; Bierlein, John; Department of Physics; Sundheimer, Michael; Faculty Member; Department of Physics; College of Sciences; N/AIn this article results of measurements of infrared parametric fluorescence in segmented KTP channel waveguides are presented, showing the dependence of optical parametric oscillator tuning curves and fluorescence conversion efficiency (parametric gain) on segmentation duty-cycle.Publication Metadata only Elastic constants of a Laves phase compound: C15 NbCr2(Materials Research Society, 1997) Chu, Fredy; Wills, Josephine M.; Chen, S. P.; Albers, Robert C; Thoma, Dan J.; Mitchell, Thomas Elliot; Department of Physics; Örmeci, Alim; Researcher; Department of Physics; College of Sciences; N/AThe single-crystal elastic constants of C15 NbCr2 have been computed by using a first-principles, self-consistent, full-potential total energy method. From these single-crystal elastic constants the isotropic elastic moduli are calculated using the Voigt and Reuss averages. The calculated values are in fair agreement with the experimental values. The implications of the results are discussed with regards to Poisson's ratio and the direction dependence of Young's modulus.Publication Metadata only Parent education and child development(Elsevier Science Bv, 1997) N/A; Department of Psychology; Kağıtçıbaşı, Çiğdem; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; N/AN/APublication Metadata only Experimental and numerical investigation of thermal effects in end-pumped Cr/sup 4+/: forsterite lasers near room temperature(Optica Publishing Group, 1997) Department of Physics; Department of Physics; Sennaroğlu, Alphan; Yılmaz, Mehmet Burak; Faculty Member; Undergraduate Student; Department of Physics; College of Sciences; College of Sciences; 23851; N/ATheory of cw thermal loading in saturable absorbers with temperature-dependent lifetime is presented. Excellent agreement with experimental data is obtained with use of chromium-doped YAG saturable absorbers.Publication Metadata only Microstructure and tribological behavior of CF/PEEK composites: effect of thermal history on matrix and surface morphologies(American Chemical Society (ACS), 1998) Sinmazcelik, T; Curgul, I; Department of Chemistry; Department of Chemistry; Yılgör, Emel; Yılgör, İskender; Researcher; Faculty Member; Department of Chemistry; College of Sciences; College of Sciences; N/A; 24181N/APublication Metadata only Laser beam propagation in a thermally loaded absorber(Optica Publishing Group, 1996) Department of Physics; Department of Mathematics; Department of Mathematics; Sennaroğlu, Alphan; Aşkar, Attila; Atay, Fatihcan; Faculty Member; Faculty Member; Faculty Member; Department of Physics; Department of Mathematics; College of Sciences; College of Sciences; College of Sciences; 23851; 178822; 253074Beam propagation in a thermally loaded absorber is analyzed by a novel method. The formulation identifies a dimensionless parameter controlling the strength of thermal effects.
