Product Description

Feature of Optical Fiber Generator

SGPL-20Q pulsed fiber laser is one of the top-class products of Sino-Galvo Technology. It helps make a leap forward when it comes to high speed and resolution laser marking assemble systems. 

Operation Guide

1. Remove the protecting cup from laser output optical head.

2. Connect laser module to control system via DB-25 interface. Please refer to Digital-Control Interface (DB-25) Description when using pins.

3. Recommended initial state of control pins:

Pin18,19,22,23 are LOW, Pin20 is within the specified range.

4. Connect 24VDC power supply with laser (+24V connect to red cable, GND connect to yellow-green cable, negative electrode connects to blue cable.)

5. In 120 seconds (warm-up time) the laser is ready for operation.

CAUTION: It is allowed to supply +24VDC before initialization of the control signals.

6. EE-Pin23 is set to HIGH.

7. Set desired power via Pin 1-8.

8. Switch the MO on applying High to the Pin18.

9. Wait 5ms.

10. The laser can be fast modulated via Pin 19. It is possible to apply HIGH and LOW sequence to switch the laser ON and OFF respectively. The laser has finite ON/OFF rise/fall times (refer to the specification). The time of the modulation should not be less than the sum of rise and fall times, otherwise laser optical response may not be as expected. The typical rise/fall times is 250us, so the modulation period is greater than 500us (corresponding to 2kHz).

11. If the EM OFF time between subsequent ON/OFF batches (jobs)is more than 20ms, it is recommended to switch OFF the MO. This will reduce the power consumption, avoid unnecessary aging of the laser and eliminate the residual MO power at the laser output.

12. After finishing the laser operation, switch OFF the BS and MO (set LOW to pin 18 and pin 19).

13. Remove all supply voltages.
