ABSTRACT

Background: Lasers have numerous applications and can be considered as one of the main technological outputs of quantum physics. Due to string theory electrons in any atom behaves as a harmonic oscillator. Thus, it is natural to solve the Schrodinger equation for harmonic oscillator in the presence of friction Schrodinger equation. Objectives: The absence of a relation between frictional effects in quantum mechanics relativity and Laser amplification led to conduct a theoretical study so as to verify the Laser amplification due to friction. String theory treats particles as harmonic oscillators. Methods In this work Schrodinger equation for frictional medium is derived, and the Harmonic oscillator solved for resistive medium. Results: The results showed no change of energy per particle. This means that energy loss due to friction changes the number of particles and does not change the energy of a single particle. This resembles inelastic scattering, which leads to atomic excitation that changes their energy by an amount (ω). Here the increase or decrease due to friction and collision is caused by the change of the number of excited atoms. Conclusions: The    Schrodinger equation for frictional medium is derived; Harmonic oscillator solution for resistive medium shows the possibility of lasing within the framework of string theory.

Keywords: Friction, lasing, String theory, Harmonic oscillator, Schrodinger equation.
