Overview: The document provides a detailed technical description of a fiber laser system, including its specifications, features, applications, and operational guidelines. The laser operates at a wavelength of approximately 1060nm with a peak power of up to 10KW and is controlled via a 25-pin interface.

Features:

Short optical pulses with high peak power and a wide range of pulse repetition rates (PRR).
High reliability and long service life.
No shadow or virtual open circuit issues when processing special materials.
Universal DB 25 Pin Interface for control.

Applications:

Industrial applications.
Scientific research.

Specifications:

Optical Characteristics: The laser operates in pulse mode with random polarization and a beam quality M² of 1.2 to 1.45. The center wavelength ranges from 1060 to 1070 nm, with a spectrum width of 8 to 15 nm. The average optical power is nominally 20W, with a power range of 10% to 100%.
General Characteristics: The laser operates in temperatures from 0 to 40°C and can be stored between -10 to 60°C. It uses air cooling and has a power consumption of 90 to 120W at 20°C.

Operation Guide:

Ensure the power supply can handle peak currents 50% higher than the operating current for short periods.
Connect the laser module to the control system using the DB-25 connector, following the pin assignments for power settings, alarms, and control signals.
Initial control pin states should be set before connecting power supplies.
After a 10-second warm-up, the laser is ready for operation. Power settings are stored via a latch pulse, and emission is controlled through specific pin signals.

Control Interface:

The laser is controlled via a DB-25 connector with specific pin assignments for power settings, alarms, and operational controls.
Power settings are adjusted using an 8-bit bus, and emission is controlled through designated pins for enabling and modulation.

Safety and Maintenance:

In case of alarms, the laser automatically switches off, and the alarm flag must be reset before resuming operation.
Ensure proper connections to avoid current loops and voltage drops that could lead to unstable operation.

Operation Guide:

The laser synchronizes with master pulses applied to pin 20, adjusting to the maximum or minimum pulse repetition rate (PRR) if the master PRR is outside the specified range.
Power settings can be adjusted during operation via pins 1-8 and latched through pin 9.
Laser emission is controlled by the state of pins 18 and 19, and residual radiation may occur depending on the configuration of EE and EM pins.
The optional red guide laser can be activated via pin 22, with specific conditions for operation.
Automatic shutdown occurs if module temperature exceeds specified limits, with alarm signals on pins 11, 12, 16, and 21.
An internal back reflection sensor can also trigger shutdown if dangerous levels of reflected light are detected.

Cut-off Power Frequency:

Pulse width, repetition rate, and power should be set according to material and marking purpose.
Maximum output power varies with pulse frequency relative to the cut-off power frequency.

Pulse Adjustment:

Hardware configuration involves a DB25 connector with specific pin assignments for data sampling and pulse duration settings.

Common Fault Treatment:

Ensure correct power supply connections and settings, and verify the condition of optical components and connections.
Power drops may result from signal interference or incorrect ground connections.

Service and Maintenance:

Only qualified personnel should service the laser, and repairs within warranty require authorization from Maxphotonics.
Changes to product design or structure may occur without notice.

Warranty Statements:

Warranty covers defects due to material or production technology within the agreed period, with specific limitations outlined.
Customers must report defects within 31 days, and third-party repairs are not authorized.
