In recent years, the theoretical research system and product development and innovation technology of HLD series lasers are becoming more and more mature, and various brand-new multifunctional products have been launched one after another, and the practical application fields of the products are expanding. The manufacturing quality and “tailor-made” design of the lasers have attracted the favor of many enterprises. Using its patented technology, Han’s Laser has independently developed CO2 lasers. After more than a decade of technology accumulation, the product performance is superior to similar products and is in the leading position in the 3C industry and other industries.
Understanding the CO2 Laser
Carbon dioxide (CO2) lasers were invented by C. Kumar N. Patel at Bell Labs in 1964 and were first used at a wavelength of 10.6 μm. It can also be referred to as a glass laser tube and is still used in the packaging coding, cutting of non-metallic materials, and in the medical aesthetic industries.
Basic Structure Diagram of CO2 Laser
Metal-tube CO2 RF lasers perform much better than glass-tube CO2 lasers and are more widely used in industrial applications.CO2 RF lasers are organized into three parts: the resonant cavity, the RF excitation, and the cooling system.
As the most technically mature, stable type of light source, CO2 lasers are also very mature in terms of process development. The 200-watt HLD series of pulsed CO2 lasers are commercially available CO2 lasers with RF excitation and resonant reed discharge cavities.
Features of the 200-Watt Pulsed CO2 Laser
1.High Power and Long Working Lifetime
Due to the short pulse rise and fall times, the peak power is many times greater than the average output power, so the high frequency RF excitation and reed discharge cavity design realize heat affected and reduces processing.

The RF discharge of these lasers does not require a ballast resistor and has a high photovoltaic conversion efficiency (up to 24%) compared to DC excitation. RF discharge excitation avoids the severe sputtering problems of DC excitation. Besides, it can be a continuous wave and high frequency. If a TTL signal is used, it can also perform frequency modulation from a few hundred Hz to several hundred kilohertz.
2.Convenient and Automatable
It utilizes an advanced metal cooling and sealing structure and selects high-quality key components for more than 20,000 hours of maintenance-free operation. The miniaturized design of the product also facilitates automation applications and can be mounted on robotic arms.
The laser’s working gas is specifically tailored to the laser for better gas discharge, more stable power, and higher purity of the laser wavelength; the integrated beam shaping system produces a circular Gaussian beam in quasi-substrate mode. The entire product is designed with a double dust protection rating and IP66 packaging rating, which provides customized solutions according to the end customer’s requirements and is also ideal for harsh industrial environments (dust, heat, water, etc.).
200-Watt pulsed CO2 lasers are mainly used for microfabrication of printed circuit boards and flexible circuit boards, precision laser cutting of plastics, scribing and drilling of ceramics, precision cutting and deposition of metals on backlighting panels, marking, engraving, scribing, and cutting of leather and various other non-metallic materials.
200-Watt pulsed CO2 lasers offer high power and energy conversion efficiencies. It also has the high optical quality of the output beam, narrow linewidth and stable operation.
