Femtosecond System with Pulse Pumping of Seed Laser and Amplifier by Using a Single Power Unit by S. A. Tikhomirov

“…The required synchronization in time the pump pulse femtosecond amplifier formation and quasi-stationary region of generated pulses in the output radiation of a femtosecond Ti:sapphire is obtained.On this basis a compact, pulse pumped monoblock laser system has been developed that can generate femtosecond pulses with a duration of 50–150 fs with an energy up to 1 mJ and a high enough pulse repetition rate (up to 1 kHz which is determined by the type of laser head and pump unit used). In the developed laser system a compact scheme of a stretcher-compressor with a single common diffraction grating is used.Laser systems of this type characterized by a relatively low cost due to the use of a single power supply unit for simultaneous pumping  of  the  amplifier  and  oscillator,  as  well  as  lower  requirements for the quality of optical elements and usage conditions due to the pulse mode of operation, are quite practical and  can  be  used  both  in  scientific research  in  the  field  of  ultra-high-speed kinetic spectroscopy and nonlinear optics, as well as in numerous technical applications, particular in the precision processing of materials, as optical  simulators  of  the  action  of  heavy  charged  particles  in  testing the radiation resistance of integrated circuits and electronic modules.…”

Study on the Stress Relaxation Behavior of Large Diameter B-GFRP Bars Using FBG Sensing Technology by Li Guo-wei, Pei Hua-Fu, Hong Cheng-yu

“…In order to study the behavior of stress relaxation, two basalt-glass fiber hybrid composite (B-GFRP) bars were developed and instrumented with fiber Bragg grating (FBG) strain sensors. It can be found that the test results reveal that the seamless pipe grip method can undertake 70% of ultimate tensile load of the B-GFRP bar, which can satisfy the requirement of stress relaxation of B-GFRP bar subjected to prestress. …”
