Diode End-pumped Laser Marking Machines

 

To meet the growing demand for industrial precision processing, we have creatively developed the diode end-pumped Q-switched laser marking machine. It is air-cooled, small, compact and low power consumption. The laser beam is TEMoo with high beam quality, high peak power and short pulse width. Excellent resonator design can keep average laser power and pulsed peak power stable & constant. This laser machine can meet the requirements of most industrial precision processing.

chiller ST-LW16-BHP

  Remark: marking head LSST can be used to replace marking head LSCT at much lower prices. Marking card is also called as D/A card.

 

 

1) Laser Head with Marking Head

 

A laser head consists of laser base (optical rail), pump module, output coupler and rear mirror with mount, beam expander, AO Q-switch cell, front plate, rear plate, and cover (option: aperture with mount). A laser marking head consists of scan mirrors, galvanometers & drive cards, galvanometer mount, scan lens (f-theta lens), marking card (PCI slot), marking software (under Windows XP) and DC power supply.

 

 

2. Q-switch Driver

 

The panel is standard 19 inch.

 

3. Diode Driver

 

The panel is standard 19 inch.

 

4. Electrical Controller

 

Including DC power supply of the marking head, replays, buttons, indicators, alarms etc.

 

5. Chiller

 

Remark:

diode driver, Q-switch driver and electrical controller can be integrated into a 19 box (called as 3 in 1 laser driver). The whole OEM laser marker just consists of a laser head with a marking head, a 19 box and an optional computer.

 

Integrated Diode-pumped Nd:YAG Laser Marking Machines (50W, 75W or higher)

 

Our DPSS laser marking systems are made by our experienced engineers. Their performance is comparable with similar  products in the world, but their prices are very attractive and competitive. These laser marking systems are widely used in industries such as electronics, semiconductor and precision machining for laser marking and trimming on moving objects, flat and cylindrical surfaces.

*
Marking field depends on scan lens (f-theta lens) once other parameters and parts are confirmed. Large field sizes demand the use of lenses of long focal length. In turn, this leads to increase focused spot size and decrease laser power density on the workpiece. Thus reasonable mark field should be carefully selected. If both small focused beam diameter (narrow line width) and large field are simultaneously required, a XY moving table is recommended for best performance.
* Other Nd:YAG lasers & customized laser marking systems available upon request.

 

Diode-pumped Nd:YAG Laser Deep Engraving System

   

The laser is specially designed for deep engraving on metals. The laser can output long pulse width & high power energy, also can output short pulse width & high peak power for the deep engraving of different materials. Through the application of new technology, the peak power is around 10 times compared to the traditional lasers, reaching 300kW. High beam quality and high conversion efficiency make the laser the best choice for deep engraving applications. The engraved depth can reach 5mm.

 

The laser can be used in deep engraving of parts of automotive and motors, hardware tools, stainless steel products, medical parts, clock and watch, industrial bearing, mould. The materials to be engraved include copper, brass, aluminum, alloy, stainless steel etc.

We can provide OEMs and system integrators with a range of high performance components and sub-assemblies of deep laser engraver at more attractive prices. These components and sub-assemblies include laser head with marking head, Q-switch driver, diode driver, marking software and chiller.
