Overview
When people hear the word "radiation", they usually think of danger. But in fact, electromagnetic radiation is everywhere in our lives and work. Laser radiation, as an electromagnetic radiation, is harmless to the human body under the premise of proper use and protection. This article will explore the classification of radiation and the characteristics of electromagnetic radiation, and introduce the safety and wide application of Inno Laser's solid-state laser.
What is radiation
Radiation refers to the phenomenon that energy propagates to the surrounding space in the form of electromagnetic waves or high-speed particles. Any object in nature with a temperature above absolute zero (-273℃) will generate radiation. Although radiation is everywhere, not all radiation is harmful to the human body.
According to the form of radiation, radiation can be divided into two categories: electromagnetic radiation and particle radiation. Electromagnetic radiation includes a wide range of frequencies from radio waves, microwaves, infrared rays, visible light to X-rays and gamma rays: while particle radiation includes high-speed particle streams such as electrons, protons, neutrons, o particles, B particles, etc.
What is electromagnetic radiation
Electromagnetic radiation covers all radiation propagated in the form of electromagnetic waves, from radio waves, microwaves, infrared rays that we are exposed to in daily life, to high-energy electromagnetic waves such as X-rays and gamma rays used in medicine and industry.
According to the energy size of electromagnetic radiation, it can be further divided into two categories
Non-ionizing radiation: low energy, unable to ionize matter. This type of radiation includes radio waves, microwaves, infrared rays and visible light. The radiation generated by devices such as mobile phones, microwave ovens and televisions in daily life is non-ionizing radiation.
Ionizing radiation: It has high energy and can ionize atoms or molecules, which may cause damage to matter. X-rays and gamma rays are typical ionizing radiation and are commonly used in medical imaging and radiation therapy.
Laser radiation is non-ionizing radiation
Laser radiation is a special type of electromagnetic radiation, whose wavelength can cover the infrared, visible light or ultraviolet range. Since lasers are usually in the non-ionizing radiation range, they will not cause ionizing damage to the human body like X-rays or gamma rays.
The uniqueness of lasers lies in the high energy density and monochromaticity of their beams. Despite the concentrated energy, the hazards of laser radiation are controllable as long as direct or reflected light is avoided from shining on the eyes or skin. This makes lasers very safe in a variety of applications.
Inno Laser Safety and Applications
Inno Laser's solid-state laser uses solid-state media as gain media to generate high-energy beams. The output radiation of this type of laser belongs to non-ionizing radiation, and its main wavelength is concentrated in the visible light and infrared range.
Since the laser radiation of solid-state lasers belongs to non-ionizing radiation, it is relatively less harmful to the human body. The safe application of solid-state lasers can be ensured through proper use and protective measures, such as wearing laser protective glasses and avoiding direct exposure. In addition, Inno Laser's solid-state lasers not only provide efficient and stable light sources, but also have the advantages of environmental protection and health and safety, and are suitable for use in a variety of application scenarios.
Inno Laser's solid-state and ultrafast lasers are widely used in industrial micromachining, high-value medical devices and scientific research due to their stable energy output and high-efficiency performance. For example, in precision machining, the company's lasers can achieve high-precision cutting and engraving: in the medical field, it is an important tool for processing implantable/interventional devices: in the field of scientific research, it provides solutions for high-speed and high-resolution photoacoustic in vivo imaging.
Summary
In summary, electromagnetic radiation is ubiquitous in our lives and work. Laser radiation, as non-ionizing radiation, is harmless to the human body under the premise of proper use and protection.
Inno Laser's solid-state lasers have shown great value in the fields of industry and medicine due to their efficient energy output and excellent safety performance. We will continue to provide safe, environmentally friendly and efficient solutions for various industries to help realize the corporate mission of "using lasers to benefit mankind".
