چکیده
Temperature-dependent thermal and spectroscopic properties of Nd:YVO4 crystal at temperatures ranging from 77 to 300 K are presented. Thermal including specific heat, expansion coefficient, conductivity investigated. The parameters, such as absorption, fluorescence, lifetime also studied. calculated absorption emission cross-sections together with relevant provide important information for designing cryogenically cooled near infrared laser. Furthermore, we experimentally explore continuous wave (CW) laser performances under various cryogenic temperatures. A maximum output power 2.13 W is obtained an incident pump 3.7 150 K, corresponding optical-to-optical conversion efficiency 57.6%.

Thermal buckling behavior of functionally graded Euler-Bernoulli beams in thermal conditions is investigated analytically. The beam with material and thermal properties dependent on the temperature and position is considered. Based on the transformed-section method, the functionally graded beam is considered as an equivalent homogeneous Euler-Bernoulli beam with an effective bending rigidity un...

In this article, a time dependent partial differential equation is used to model the nonlinear boundary value problem describing heat transfer through a radial porous moving fin with rectangular profile. The study is performed by applying a numerical solver in MATLAB (pdepe), which is a centered finite difference scheme. The thermal conductivity and fin surface emissivity are linearly ...
متن کاملThermal Properties Measurements Using Laser Flash Technique at Cryogenic Temperature
In the frame of the Italian TRASCO program, we have studied the possibility to stiff SC cavities by deposition of thermal sprayed copper on thin niobium. We have investigated the use of the Laser Flash technique to test the thermal conductivity in the normal direction of deposited copper with the Pure Coat technique. The use of Au-Fe/Cromel P thermocouples as temperature sensors, motivated by t...
