High-Power High-Brightness Lasers
High power high brightness diode lasers are gaining more and more interest for applications previously dominated by expensive and inefficient solid-state lasers due to their better efficiency, brightness and compactness. The significant fact about conventional high brightness optical sources is that they exhibit about an order of magnitude higher brightness than broad-area semiconductor lasers....
متن کاملLaser Cooled High-Power Fiber Amplifier
A theoretical model for laser cooled continuous-wave fiber amplifier is presented. The amplification process takes place in the Tm 3+ -doped core of the fluoride ZBLAN (ZrF4-BaF2LaF3-AlF3-NaF) glass fiber. The cooling process takes place in the Yb 3+ :ZBLAN fiber cladding. It is shown that for each value of the pump power and the amplified signal there is a distribution of the concentration of ...
متن کاملHigh power 2 µm femtosecond fiber laser.
A high power polarization maintaining femtosecond Tm-doped fiber laser system is demonstrated. A chirped fiber Bragg grating with normal dispersion was used to compensate the anomalous dispersion from the regular fiber in the 2 µm seed oscillator to generate mode locked pulses with a pulse repetition rate of 30.84 MHz. After chirped pulse amplification, an amplified power of 78 W was obtained. ...
متن کاملInvestigation of Thermal Dispersion and Thermally-Induced Birefringence on High-Power Double Clad Yb:Glass Fiber Laser
In this work the effects of heat generation on the modes of Yb:Glass double clad fiber laser were investigated. The thermal dispersion and thermally-induced birefringence were considered when the gain medium becomes an anisotropic medium. The results showed considerable modifications of laser modes profiles, in particular for transfer magnetic (TM) and transfer electric (TE) modes which their p...
متن کاملHigh Power, High Brightness Proton Accelerators*
Proton accelerators were originally developed for nuclear physics experiments as an alternative to radioactive source or cosmic rays. From the earliest days, the energy of the proton has been the most important design parameter of the accelerator builders. As early proton accelerators one can name the Van de Graaff[2] and Cockcroft-Walton[3] devices. They are electrostatic machines, of which th...
