Param(F3) Configuration: Laser Control

Laser type:

Co2: It indicates that current laser size is Co2 laser.

YAG: It indicates current laser size is YAG laser.

Fiber: It indicates that current laser size is fiber laser.

SPI_G3: It indicates that current laser size is SPI laser.

Note: this function only support USBLMC control card.

PWM:

Enable PWM signals: The PWM signal will be output from Control Card.

Max. PWM freq: the max frequency of the PWM signals.

Enable Tickle: Let the preionization signals active for some CO2 laser sources.

Pulse Width: the pulse width of the preionization signals.

Pulse Period: the frequency of the preionization signals.

Use Digital Q-switch driver: This function is for digital Q-switch. If check this function, the output port 1 and 2 cannot apply in other purpose. This mode mainly design for Digital Q driver of Guilin Xingchen.

Q-switch Open when F.P.K End: If Checked, the Q-switch modulation signal will begin pulsing after the FPS delay has expired. Otherwise Q-switch pulsing begins at the end of the Start TC delay and coincidentally with the beginning of the FPK signal.

First Pulse Killer ( F.P.K): the lasting time for the first pulse suppression.

Pulse width reverse: Reverse the PWM signal.

Enable Power Analog Output: Enable the control card to output analog signal which used to control laser power.

Power Mapping: This is power emendation function, used to set the power percentages of the customized and the corresponding one, as Figure 10-26 shows. If the customized power percentage is not in the displays of the Power dialog box, the system will pick the linearity margin values.

Enable Frequency Analog Output: Enable the control card to output analog signal which used to control Q-Switch frequency.

Frequency Mapping: This is frequency emendation function, used to set the frequency percentages of the customized and the corresponding one, as Figure 10-27 shows.

Enable CO2 FPK: can wipe off the burn-in effect at the start.

Enable CO2 Pulse Mode: When selected, the point dist will appear in the parameter, and the software will be calculated the scan speed according to the setting. The marking points will meet the setting with this speed.

Enable Analog First Pulse Killer:

Max: Max voltage of analog FPK.

Min: Min voltage of analog FPK.

T1: Time that the FPK signal changes from Max voltage to Min voltage, or reverse.

T2: If the time gap between the laser off and laser on is less than T2, the FPK would not output.

The direction that the FPK changes.

About the T1 and T2 we can see figure：

After selecting fiber, the type of fiber laser will appear in the right, for example, ipg, ipgm, quantel, raycus, and the corresponding frequency range and MO delay will appear.

Test laser

It is used to test whether laser is working normally or not. Hit “test laser” button presenting dialog box shown in graph:

Fill in the frequency, power, pulse width and laser on time and hit “Laser on”. After that LASER open and it will close when reach the appointed time.
