ML-5120A is a direct diode laser with maximum output of 120W and designed for high energy efficiency. The laser light is created directly from the diodes and does not need amplification in crystals such as Nd:YAG or Nd:YVO4. The output is directly used for thermal processing such as plastic welding and soldering applications, by using newly equipped function of temperature control.
▶ Real-time Power Feedback Control
The laser output in the lamp-pumped module is monitored in real time. The monitored laser output is compared with the set waveform and power is fed back in real time, varying the energy input to the lamp to reproduce the set waveform and obtain the ideal laser output waveform.
▶ Waveform control
Equipped with a "fixed mode" that features three-level waveforms, and a "flex mode" to provide more complex waveforms.
▶ Power monitor
Laser energy (J) and average power (W) are monitored to detect abnormalities.
▶ Color LCD touch panel
The touch panel can be detached from the main unit and operated by hand.
▶ External communications
Configuration of parameters and monitoring of performance can be carried out from a separate location.
- Type: RS-485 compliant, asynchronous, full duplex
- Data speed: 9600, 19200, 38400 bps
This feature avoids marks at the end of seam welding and provides a beautiful finish even for overlapping circumference seam welding sections.
▶ Forced Air Cooling System
The air cooling system is available. No water and piping are necessary.
