We report poor fluorinated graphene sheets produced by thermal exfoliation embedding in carboxymethylcellulose polymer composite (GCMC) as an efficient mode locker for erbium doped fiber laser. Two GCMC mode lockers with different concentration have been fabricated. The GCMC based mode locked fiber laser shows stable soliton output pulse shaping with repetition rate of 28.5MHz and output power of 5.5 mW was achieved with the high concentration GCMC, while a slightly higher output power of 6.9 mW was obtained using the low concentration GCMC mode locker. © 2015 AIP Publishing LLC.

High Temperature | Year: 2011

Thermophysical and hydrodynamic processes in a spherical vapor bubble and the surrounding fluid are studied at an increase in the external pressure using the method of numerical simulation. The study was carried out based on a mathematical model belonging to the class of homobaric bubble models (uniform bubble pressure at nonuniform temperature and density). The numerical simulation yielded data on the key characteristics of vapor bubble compressions in water under different initial conditions. © 2011 Pleiades Publishing, Ltd.

Atomic Energy | Year: 2010

A qualitatively new stage in the development and practical application of atomic energy in space is linked with the use of multipurpose high-capacity propulsion-power modules. Their design based on a nuclear powered propulsion facility in the megawatt range has been approved and accepted for implementation. In this article, the facility is described, the principles of operation of the facility as a whole and its individual subsystems are examined, and the proposed characteristics and mass of the structural elements are presented. The advantages of using atomic energy in the power-plant-motor variant, including for manned flight to Mars, are shown. © 2010 Springer Science+Business Media, Inc.
