be operated in continuous wave (CW) or Q-switched mode, which produces short pulses of high-intensity light.<\/li>\n<li>Using laser diodes that emit 1064 nm light directly or through a volume Bragg grating (VBG) that stabilizes the wavelength.\u00a0These diodes can have free space or fiber coupled outputs and can be single-mode or multi-mode.<\/li>\n<li>Using fiber lasers that use a doped

of 1064nm Laser<\/h2><\/div><div class=\"fusion-text fusion-text-5\"><p><span style=\"font-weight: 400;\">Some advantages of 1064nm wavelength are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It can penetrate deeper into biological tissues than visible or ultraviolet light, which makes it suitable for medical applications such as laser hair removal, treating vascular skin lesions and laser-induced thermotherapy<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It can interact strongly with many materials, such as metals, ceramics and plastics, which makes it useful for material processing and analysis such as laser cutting, welding, drilling and laser-induced breakdown spectroscopy<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It can be easily converted to other wavelengths by nonlinear optical processes, such as frequency-doubling, tripling or mixing. <\/span><span style=\"font-weight: 400;\">For example, a 1064nm beam can be converted to a 532nm green beam or a 355nm ultraviolet beam by using a nonlinear crystal<\/span><span style=\"font-weight: 400;\">. <\/span><span style=\"font-weight: 400;\">This allows for applications such as ultraviolet lithography and LASIK eye surgery<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It can be efficiently coupled into optical fibers, which enables flexible delivery and remote operation of the laser<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Some disadvantages of 1064nm wavelength are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It has much lower scattering intensity compared to shorter wavelengths, which means that it requires higher laser power and longer exposure times to achieve the same signal level. This increases the risk of sample damage and limits the sensitivity of some techniques such as Raman spectroscopy.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It has lower brightness and resolution than shorter wavelengths, which means that it cannot achieve precise and accurate patterning or correction of very small features. <\/span><span style=\"font-weight: 400;\">This limits its applications in nanotechnology and microfabrication<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is invisible to the human eye, which makes it harder to align and focus the beam. <\/span><span style=\"font-weight: 400;\">It also poses a higher safety hazard than visible light, as it can cause eye damage without being noticed<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<\/ul>\n<\/div><div class=\"fusion-title title fusion-title-6 fusion-sep-none fusion-title-text fusion-title-size-three\"><h3 class=\"fusion-title-heading title-heading-left fusion-responsive-typography-calculated\" style=\"margin:0;--fontSize:24;line-height:1.3;\">A comparison of 1064nm and 808nm laser<\/h3><\/div><div class=\"fusion-text fusion-text-6\"><ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">1064nm laser has a lower absorption by melanin than 808nm laser, which means that it can penetrate deeper into the skin and target the hair follicle more effectively. <\/span><span style=\"text-decoration: underline;\"><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/11896773\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">However, it also means that it requires higher power and longer exposure time to achieve the same result as 808nm laser<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">1064nm laser has a lower scattering intensity than 808nm laser, which means that it can produce a more collimated and focused beam. <\/span><span style=\"font-weight: 400;\">However, it also means that it has lower sensitivity and resolution for some techniques such as Raman spectroscopy<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">1064nm laser has a higher versatility than 808nm laser, as it can be easily converted to other wavelengths by nonlinear optical processes. For example, it can be frequency-doubled to produce a 532nm green beam or frequency-tripled to produce a 355nm ultraviolet beam. <\/span><span style=\"font-weight: 400;\">This allows for more applications such as ultraviolet lithography and LASIK eye surgery<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">1064nm laser is more suitable for darker skin types than 808nm laser, as it has a lower risk of causing skin damage or pigmentation. <\/span><span style=\"font-weight: 400;\">However, it is also more dangerous for the eyes, as it is invisible to the human eye and can cause eye injury without being noticed<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Therefore, it is not possible to replace 1064nm laser with 808nm laser in all applications, as they have different advantages and disadvantages depending on the purpose and the desired performance. Some applications may require a specific wavelength or a combination of wavelengths to achieve the best results. <\/span><span style=\"font-weight: 400;\">For example, laser hair removal may use a triple-wavelength diode laser that combines 755nm, 808nm and 1064nm lasers to target different hair types and skin tones<\/span><span style=\"font-weight: 400;\">.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":11959,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-11744","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v18.7 (Yoast SEO v25.8) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>1064nm Laser - SZLASER<\/title>\n<meta name=\"description\" content=\"1064nm laser is a type of infrared laser that emits light at a wavelength of 1064 nanometers.
