5w UV laser prints black fonts on yellow heat shrink tubing

In recent years, with the continuous development of technology, ultraviolet lasers have been widely used in many fields. One application is black lettering on yellow heat shrink tubing. This technology is widely used in various industries such as electronics, communications, medical and military.


The process of using a 5w UV laser to print black fonts on yellow heat shrink tubing mainly relies on the characteristics of high energy density and high-precision control. The ultraviolet laser has a short wavelength and high energy, which can quickly heat the material on the heat shrink sleeve and cause a chemical reaction, making it darker in color and forming black fonts.


In actual operation, the parameters of the UV laser need to be finely adjusted first. This includes laser power, pulse width, pulse repetition rate, etc. Only by adjusting these parameters to the optimal state can the best coding effect be obtained. In addition, factors such as the material, thickness and color of the heat shrink sleeve need to be considered, as these factors will affect the coding effect and quality.


In addition, when using a UV laser to print black fonts on yellow heat shrink tubing, you need to pay attention to safety issues. UV lasers have extremely high energy and can cause harm to the human body if not operated properly. Therefore, you must wear protective equipment such as goggles and gloves during operation, and avoid direct exposure of the laser to your skin or eyes.


In short, using a 5w UV laser to print black fonts on yellow heat shrink tubing is an efficient and accurate coding technology. Although you need to pay attention to adjusting parameters and safety issues during the operation, as long as you operate it correctly, you can obtain the ideal coding effect. This technology has broad application prospects in various industries.

S9-Y series solid state pulsed UV laser is ultra compact. The whole part of power supply is integrated into the laser head. This makes the size of the laser more smaller, and the integration into a system more easier and convenient. S9-Y series is of short pulse width(<12ns@30k),superior beam quality(M²<1.2) and perfect laser sport quality(beam circularity>90%).



S9-Y series uv laser characteristics:   

1. 355 nm output wavelength, Up to 200 Hz repetition rate; laser power ranging from 3w-10w; Continuous tuning of repetition rate while maintaining constant pulse energy, superior beam pointing and energy stability make the S9-Y the first choice for micromachining, marking and thin film removal applications 


2. Exceptional beam quality (M²<1.2) ,absolutely assured in all repetition rates; relatively short pulse width <12ns@30 with little heat transfer to surrounding material; perfect beam spot quality(Beam Circularity>90%) 

Close to Gaussian smooth beam profile with low value M² < 1.2 and good focusability are beneficial for applications such as
