Recently, a Japanese research team has developed a vertical deep ultraviolet emitting semiconductor laser device based on AlGaN, which is expected to be applied in laser processing, biotechnology, and medical fields.As is well known, ultraviolet (UV) is an electromagnetic wave with a wavelength range of 100 to 380nm. These wavelengths can be divided into three regions: UV-A (315-380 nm), UV-B (280...
The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
Recently, the term CTC technology has become a hot topic in the new energy vehicle industry. During the relatively slow period of electrochemical innovation, this structural innovation effectively helped the new energy industry reduce costs and increase efficiency, while also increasing the range of new energy vehicles to a certain extent. However, recently the author learned that the concept of C...
