In recent years, the application scenarios of VCSEL burst out, so that laser chip ushered in the development of the best time. With the maturing technology of 808nm VCSEL laser chip, its advantages such as stable wavelength, low divergent circular beam, high efficiency, no need for water cooling, low cost and so on, perfectly fit the development trend of hair removal products to commercialization, home, light weight, is leading the reform of a new generation of household handheld laser hair removal device, becoming one of the new favorite in the field of consumer electronics.
VCSEL is a kind of vertical cavity surface emitting laser, which is very different from the traditional EEL laser in structure, which makes up for the disadvantages of traditional laser hair removal to a certain extent, and has unique advantages:
Stable wavelength, small temperature drift coefficient, no need for water cooling;
Luminous vertical substrate direction, easy to optical shaping, light path is simple;
The beam energy is uniform, will not produce local power too high burn skin phenomenon;
The size of active area is very small, which can achieve high packaging density and low threshold current, suitable for hand-held;
It is produced by wafer processing with low cost (traditional EEL requires a series of processes, such as cleavage, coating, packaging, etc.).
At present, the Brandnew 808nm VCSEL laser chip has been applied in batches in the client. With its advantages of small size, high beam quality, high electro-optical conversion efficiency, long life, low cost, stable performance and other advantages, it has become the best choice for the production and manufacture of household hand-held hair removal instrument, which is widely popular.
Considering the practical application requirements of end customers, CSEL can not only provide customers with 808nm VCSEL chip and high power package module. We can also provide customized solutions according to customers' requirements. By adjusting the power, wavelength, layout size and package design, we can quickly respond to the application requirements of different end customers and help customers win the market.
