We have primarily a comparison between the
Diode Pump Laser Marking Machine and
YAG Lamp Pump Laser Marking Machine.
Both of
Diode Pump Laser Marking Machine and
Lamp Pump Laser Marking Machine produce laser light on basis of Nd:YAG(Neodymium-doped Yttrium-Aluminum-Garnet) crystal as laser material that can be converted from the visible light of 808NM to invisible laser light with a wavelength of 1064nm, but another factor of the output laser light is laser pump source which can make the crystal rod put out laser light, the
Diode Pump Laser Marking Machine send out light waves of 808nm by the use of semiconductor diode, and the
Lamp Pump Laser Marking Machine use krypton lamp to send out light. Therefore, the conversion efficiency of the
Diode Pump Laser Marking Machine is much higher than the
Lamp Pump Laser Marking Machine.
Advantages of
Diode Pump Laser Marking Machine are as follows:
Third,
Diode Pump Laser Marking Machine will have a better marking affects.
Since almost all semiconductor diode transmit one same wavelength light, as a result, the laser beam has better monochrome, better marking mode, more energetic and better marking results.
Second, the diode laser marking machine has much smaller size than the
YAG Lamp Pump Laser Marking Machine.
It is said that the
Diode Pump Laser Marking Machine produce less waste energy than YAG series Lamp Pump Laser Marking Machine, smaller cooling system is enough, usually a refrigerator may be sufficient, while the Lamp Pump Laser Marking Machine will need more than two or more cooling system and cooling pump for providing a water flow.
Therefore, the
Diode Pump Laser Marking Machine produced less noise during working than the
Lamp Pump Laser Marking Machine,while large cooling unit will produce more energy from
YAG Lamp Pump Laser Marking Machine, especially in summer high temperature, excess calories will make the working environment worse and worse, and the increasing air regulator to balance temperature will no doubt increase the production costs.
