分析了形成激光的诸要素,统一地理解了普通(以原子、分子或凝聚态物质为介质的)激光和自由电子激光的运作机制.由此认识了实现γ射线激光的困难和解决办法,即让带电粒子在普通激光中摆动,再配以适当的“共振”和“抽运”机制.为了进行精确可靠的分析我们建立了激光中的量子电动力学.她与真空中的量子电动力学等价,因此是当今最可靠的物理理论.由此明确得出的结论是,一束适当能量的单能直线前进的电子与一束单色平面波普通激光迎面相撞将产生γ射线激光,称为量子自由电子激光.当然,这是理想条件下的理论结论.然而协同学(synergetics)告诉我们,在实际条件逼近理想条件的过程中会有一临界点,越过这一点,诱致辐射的正反馈会导致一雪崩式的过程,电子束与普通激光碰撞产生的γ射线束遂相变为γ射线激光.
This paper analyzes the various factors that form the laser and unifies the operation mechanism of ordinary (free atoms, molecules or condensed matter) lasers and free electron lasers, so as to realize the difficulties and solutions of realizing the gamma rays lasers Let the charged particles swing in the normal laser, and then with the proper “resonance” and “pump” mechanism.In order to carry out the accurate and reliable analysis we establish the quantum electrodynamics in the laser.Her and the vacuum quantum Electrodynamics and is therefore the most reliable physical theory of the day, and it is thus clearly concluded that a properly energetic, monoenergetically linear advancing electron colliding with a monochromatic plane wave ordinary laser will produce a gamma ray laser , Which is called a quantum free electron laser, which is, of course, a theoretical conclusion under ideal conditions.However, synergetics tells us that there is a critical point in the process of approximating ideal conditions to actual conditions, beyond which the positive The feedback will result in an avalanche-like process, and the γ-ray beam produced by the collision of the electron beam with an ordinary laser will phase change into a γ-ray laser.
