Here we will mainly introduce the comparison between
Diode-pump Laser Marking Machine and YAG Lamp-pump Laser Marking Machine.
Diode Pump Laser Marking Machine and Lamp-pump Laser Marking Machine are all based on the ND: YAG (neodymium-doped yttrium aluminum garnet) crystal as a laser-produced material, which can be converted 808nm visible laser to 1064nm not visible laser light, but another more critical factor of the output laser is the laser pump source which can make the crystal rod put out laser light, the
Diode-pump Laser Marking Machineuses semiconductor diode-pumped to send out 808nm light waves; and lamp-pump use krypton lamp to issue lamp pump, but light sent out from the krypton lamp has wider light spectrum, with only one slightly larger peak in the 808nm Department, the light in other wavelengths eventually turned into useless heat dissipation out. Therefore, the conversion efficiency of Diode-pumped Laser Marking Machine is much higher than the Lamp-pump Laser Marking Machine. Benefits of
Diode Pump Laser Marking Machine are as follows:
First,
Diode-pump Laser Marking Machine has no need to change krypton lamp.
The life span of semiconductor diode is quite long, its rated working hours is larger than ten thousand hours, while the lifetime of krypton lamp is only several hundred hours (usually about 400-600 hours), as a result, lamp pump Laser Marking Machine need to change krypton lamp at work for some time, especially for the metal marking, more energy will be needed, the lifetime of krypton will be more affected.
Therefore,
Diode Pump Laser Marking Machine is also called maintenance-free Laser Marking Machine, which means no working materialconsumption, no maintenance for quite a long time. According to different production tasks of different users, the lifetime of
Diode-pump Laser Marking Machine can guarantee between one and three years.
