UV lasers are highly sophisticated optical devices which emit short wavelengths of ultraviolet light. 355nm UV lasers have attracted a lot of attention because of wide applications in biomedicine, material processing and optical communication.
355nm ultraviolet laser is obtained by frequency conversion of pump laser (generally 1064nm infrared laser) through frequency doubling crystals. The frequency doubling crystal usually adopts second harmonic crystal like KDP (potassium dihydrogen phosphate) or BBO (β-barium borate), able to shorten the wavelength of the pump laser to 355 nm. This laser has teh characteristics of high beam quality and narrow spectral line width, which can produce the UV laser pulses of high energy and high repetition frequency.
Laser fine micromachining is the process of laser processing of materials and devices with accuracy of micrometers. With the advantages of high single photon energy of UV laser, high material absorption rate, good focusing performance and narrow pulse width, 355nm UV nanosecond laser has occupied large portion in the field of fine micromachining.
355nm UV laser has wide range of applications in the biomedical field. Its short wavelength allows it to penetrate the surface of biological tissues and interact with target molecules. As a result, it is widely used in cellular microscopy imaging, laser surgery and cancer treatment. For example, in dermatology, 355nm UV lasers can be used to treat diseases such as vitiligo and vascular lesions with very good efficacy.
355nm UV lasers also have important application value in the field of material processing. Due to higher beam quality and smaller spot size, it can achieve high precision processing of microfine structures. Especially in semiconductor manufacturing and lithography processes, 355nm UV lasers are widely used in wafer etching, nanofabrication and manufacture of microelectronic devices.
355nm UV lasers also show great potential in the field of optical communication because of rapid development of fibre optic communication technology. Its short wavelength and high energy make it an ideal laser source for fibre optic transmission of high speed and high capacity. In addition, 355nm UV lasers can also be used for research and development of key technologies such as fibre optic sensing and fibre optic amplification.
Due to the continuous development of science and technology, the potential applications for 355nm UV lasers in various fields will expand. Firstly, in the biomedicine sector, the demand for UV lasers rises continuously because of increasingly sophisticated cancer treatments and cell research. Secondly, in material processing, the rapid development of microelectronic devices will lead to a constant need for high precision processing equipment. Finally, in the field of optical communication, the increasing growth of 5G and optical communication technology necessitates high speed and highenergy laser sources, which will stimulate the advancement of 355nm UV lasers.
