Product Description:

The JPT pulsed fiber laser adopts the MOPA (Master Oscillator Power Amplifier) structure, where the main oscillation uses a semiconductor laser as the seed source, and the power amplification is achieved through a traveling wave fiber amplifier. This MOPA fiber laser has the characteristics of independently adjustable pulse width and frequency. It can maintain a high and stable peak power output even when the pulse width and frequency are changed. It is suitable for industrial laser marking, precision processing and other applications. Provides an ideal light source.
 

This type of fiber laser is pumped by fiber coupled output semiconductor laser, which has higher energy conversion efficiency; and the laser adopts an air-cooled system, the heat dissipation structure is more compact, the volume is smaller, and it is more portable; and the integrated all-fiber design , So that the system is free of maintenance and convenient for customers to use.
 

This type of fiber laser uses 48VDC power supply and adopts standard DB25 interface mode, which has good compatibility. Compared with similar products, JPT pulsed fiber laser can adjust the pulse width and frequency within a certain range, and can maintain a stable high peak power output, which is particularly advantageous in high-speed marking applications.
 

Install the power cord provided with the laser box between the 48V DC power supply and the interface, and ensure that the DC power supply can provide sufficient output power. When connecting, please connect and lock the connectors as shown in Figure 9 and Table 6. The“Main+" and "Control+" on the power cord connector end are 48VDC positive, and "Main-" and "Control-" are 48V DC negative. "Earth" is the chassis ground wire.

“Main+" and "Main-" are the power supply pins for laser pumping, and "Control+"  and “Control-" are the power supply pins for the control circuit. If independent power supply isn’t required, the two power supplies can be used in parallel.

The power interface of the laser is a DB-7W2 plug (male), and the pin assignment is shown in the following table:

Note 1: The voltage amplitude requirements of the DB25 control interface: high level range >4.6V, <5.4V; low level range≥0V, <0.5V.

Note 2: The priority of the red light PIN22 signal is higher than the MO and PA signals. When the PIN22 signal is high, the MO and PA signals will be automatically closed internally. After the PIN22 signal is low, restart the MO and PA to emit laser;
