UV laser are mainly divided into gas UV laser and solid ultraviolet solid-state lasers. Under the action of the pump source, the working medium reaches the excited state by absorbing external energy. After population inversion, the gain is greater than the loss, and the light is amplified. The partially amplified optical feedback continues to be excited, creating oscillations in the resonator cavity, resulting in lasing. The gas medium mainly uses pulse or electron beam discharge. Through the collision between electrons, the gas particles are excited from the low energy level to the high energy level, and the excitation transition is generated, thereby obtaining the ultraviolet laser. The solid medium is a nonlinear frequency-doubling crystal, and after one or more frequency conversions, an ultraviolet laser radiating outward is generated.
UV laser processing has many advantages and is also the preferred technology for the development of scientific and technological information. First, the ultraviolet laser can output ultra-short-wavelength laser light, which can precisely process ultra-fine materials; secondly, the "cold treatment" of the ultraviolet laser will not destroy the whole of the material itself, but only treat the surface; it cannot effectively absorb visible light and infrared lasers, result in inability to process. The biggest advantage of UV light is that basically all materials have a broad absorption of UV light. UV lasers, especially solid-state UV lasers, are compact, small, easy to maintain, and easy to mass produce. UV laser are widely used in medical biological material processing, criminal case forensics, integrated circuit boards, semiconductor industry, low-light components, surgery, communications and radar, laser processing and cutting and other fields.
