- Multiple Control Modes: The GUI offers different control modes, including Full Control Mode and Free Control Mode.
- Full Control Mode (GUI Ctrl): In this mode, all parameters (EG, power, frequency, pulse width, PA, MO) are managed through the internal control module. Changes made in this mode are preserved after power off.
- Free Control Mode (Free Ctrl): This mode allows users to choose parameter control individually. All settings in this mode are preserved after power off.
- Ctrl MO Mode: This mode allows users to lock a specific frequency or output power individually when external signal control is not desired. The "MO" button can be used to switch the control of the MO signal.
- Parameter Setting and Emission: Users can set parameters such as Lock PRR, Def pulse, Simmer, Lock P, and RedPower. The software allows for easy modification and saving of these settings.
- Pulse Width Control: The laser supports precise pulse width control, which is critical for various applications. The GUI provides options to adjust pulse width, and the system can handle different pulse width control sequences.
- External Frequency Control: The laser can be synchronized with an external frequency signal, allowing for integration into more complex systems. The control card has optimized the external frequency signal, which can be used in this mode.

- DB25-MO: Monitors whether the laser currently receives MO signal, and the green light indicates the status of received signal.
- Laser power: Displays the power percentage of the pump source current conversion.
- Circuit temperature: Monitors the current laser circuit module temperature.
- Optical path temperature: Monitors the temperature of the optical path module of the current laser.
- Pulse width: Monitors the working pulse width parameter of the current laser.
- Frequency: Monitors the current laser operating frequency parameter.
- Error Handling and Warnings: The system provides warnings and error messages to alert users to potential problems, such as incorrect power supply voltage, damaged cables, or issues with the laser product itself. This helps in troubleshooting and preventing further damage.
- Preventive Measures: The manual outlines preventive measures to ensure the laser's longevity, such as:
- Making sure the 24VDC power supply is connected correctly.
- Ensuring the bending diameter of the fiber cable is larger than 15cm.
- Adjusting the speed of the fan to ambient temperature to maintain minimum 10cm air gaps behind and in front of the fiber laser.
- Ensuring proper ventilation distance and wrong air flow direction.
- Avoiding "thermal lens effect" by using ordinary K9 glass optical lens in medium and high power range applications.
- Keeping the fiber laser source clean, especially the laser output window, and covering the output window when it's exposed to the open environment.
- Dust on the window can cause heat and damage the lens, which results in output power decrease.
- Warranty and Service: Warranty and service terms are provided in the User's Manual and are subject to official contract.
