HTL QT Desktop Laser System 3


Compact, Desktop Version of Hai Tech Lasers’ QT Fiber Laser Marking System

The HTL QT Desktop Laser System is a compact, desktop version of Hai Tech Lasers’ QT Fiber Laser Marking System. This ready to use fiber laser marking system is ideal for industrial applications. It provides permanent and non-contact marks on practically any material. The system is compatible with a wide range of parts and sizes.

The HTL QT Desktop Laser Marking System uses state-of-the-art fiber optic technology enhanced with rare earth elements, multiple laser diodes, Bragg networked mirrors, and a high-tech F-Theta lens. These unique and highly specialized components work together to create a more precise and accurate laser system that can be used for marking a broad range of metal and non-metal materials. The HTL QT Desktop Laser Marker is less expensive, easier to move, and simpler to install than traditional laser marking equipment.

How Fiber Laser Systems Work

Fiber optic laser systems operate under the same principles as most lasers. Generated light is focused through the use of mirrors and lenses into a compact, focused beam that uses heat to change the surface of a material. In order to be effective, the light generated by a laser system must consist of parallel rays of a single monochromatic light wavelength, and the light waves must move in synchrony. 

In general, laser arrays consist of a light source, an amplifier or gain medium, and a set of two mirrors inside the gain medium. The source sends light into the gain medium, and the light is then amplified by the mirrors until it achieves the wavelength and synchronicity necessary for a laser beam.

Fiber lasers present several differences from other laser arrays, as follows:

  • Rare earth elements. The gain medium is composed of fiber optics treated with rare earth elements that help to keep the light wavelength within a specific spectrum. 
  • Laser diodes. The generator consists of multiple laser diodes, which convert electrical current directly into light, which is directed into the gain medium.
  • Bragg mirrors. The mirrors in the gain medium of a fiber laser are made of varying thicknesses and slits that allow for additional light refraction, for more control over the beam wavelength.
  • F-Theta lens. Fiber laser marking systems use a specialized F-Theta lens, which allows for more accurate focus of the laser beam onto the surface of the material. While with other lenses, the beam’s placement can be distorted by its travel through the gain medium, an F-Theta lens can be used to better control the focus of the beam, for more precise marking.


Difference Between Fiber Laser Systems and CO2 Laser Systems

As fiber optics technology continues to advance, it gains numerous benefits over more traditional CO2 laser systems.

Fiber Laser Attributes

  • Energy efficiency. Fiber lasers exhibit extremely high electronic-to-optical efficiency, for significantly lower power consumption than its CO2 counterparts. 
  • Compact size. Fiber laser arrays are smaller and less bulky than other laser marking systems, making them easier to transport and install as needed.
  • Laser beam quality. Fiber laser systems offer finer control over laser beam wavelengths, for a higher quality beam than other methods.
  • Low maintenance. Not only are fiber laser systems energy efficient, they are inexpensive to equip and maintain when compared with other laser marking equipment.
  • Material versatility. Fiber laser systems can be used to mark a wide variety of metal and non-metal surfaces.

CO2 Laser Attributes

  • Low energy efficiency. CO2 lasers are more expensive to operate than fiber lasers. Their much lower electronic-to-optical ratio results in higher energy usage and increased overall costs. 
  • Limited materials. The basic principle of CO2 lasers is the use of carbon dioxide to break organic bonds, thereby altering the material at a molecular level and creating the desired mark. Unfortunately, this means that CO2 lasers can only be used on materials that have carbon-oxygen organic bonds, such as plastic, wood, paper, and ceramics.
  • High maintenance. Instead of using diodes, CO2 lasers use a gas filled tube to convert electricity into optical energy. Not only is the process less efficient than fiber laser methods, the equipment requires frequent maintenance and replacement.

Designed To Meet the Customers’ Needs in a Compact Footprint

Our Desktop unit comes with a 6″ Z-Axis focus control, 20W Fiber Laser, and 7″x7″ marking area. This configuration can be used to mark all but the largest and most difficult marking jobs.
