Tyson 808nm VCSEL laser diode application case-laser hair removal
With the development of semiconductor laser technology, products using VCSEL as the core device show a lot of advantages, and in the field of laser beauty, it has increasingly won the recognition and favor of consumers worldwide. At present, the mainstream hair removal instrument on the market uses a 808nm laser as the core component.
Compared with OPT laser hair removal, it only has a better effect on black hair. Hairs of other colors, such as yellow hair and white fluff, are weaker and have a slight tingling sensation. 808nm semiconductor laser wavelength can target melanin for precise and selective hair removal treatment. It can efficiently remove black, yellow, white, brown and other color hair, fast and accurate. The melanin absorption effect is particularly good, satisfying customers' whitening and beauty demand.
At present, domestic high-end semiconductor laser chips mainly rely on imports, and the market demand is strong. Therefore, it is of great significance to carry out independent research on high-end semiconductor laser chips. Tyson's timely launch of high-performance 3W, 6W, 10-12W 808nm VCSEL chips has won favor and praise from customers in the market.
808nm VCSEL laser diode has obvious advantages: electro-optical conversion efficiency is as high as 45%, flat package and TO package are optional, small size and light weight; high output power, small temperature influence, low wavelength drift as low as 0.07nm / ℃, stable performance and long life 50,000 hours.
With 808nm VCSEL laser diode as the basic device, it can be made into a 808nm high power vertical stacked semiconductor laser module, which is used in semiconductor laser hair removal products and other fields. It can provide multiple laser Bar vertical stacking packages to form a high power laser output. High-density laser bar stacking technology, with a small bar spacing, enables the module to obtain high-brightness laser output while maintaining a small size, providing efficient work.
In addition to 808nm laser diodes, Tyson also has 850nm and 940nm VCSEL laser diodes. Diverse package forms, compact package structure, easy to integrate, TO package market application is mature, and single point and array are optional to meet different power and spot shape requirements.
