Laser Diode Cut Module

Product Description

Model:50w  Laser Diode Cut Module

Product Name: Laser Diode cut module

Material of outer holder: Metal

Color of Outer holder: Grey and black

Function & Application: Laser marking machine，laser welding machine, laser cutting machine and other applications.

Product Feature

The working principle of semiconductor module is excitation mode, which uses semiconductor materials (both electrons) to transit between energy bands to emit light. Two parallel mirrors are formed on the cleavage surface of semiconductor crystals as mirrors to form a resonant cavity, which can amplify the light oscillation, feedback and radiation to produce light, and output laser.

Semiconductor module laser has the advantages of small size, light weight, reliable operation, low power consumption and high efficiency.

FAQ

Installation and Using Method

1.Air Circumstance

If dusts or impurities adhere to an optical component on the area, high laser energy density can damage this area, such as crystal ends. To prevent dusts from polluting rod ends of the YAG crystal or entering the cavity, clean air or sealing the laser system is necessary.

2.Water cooling system

● Pure water is required. Filtration should be added to the water cooling system. Check water quality routinely, change water or filtrate water immediately when impurities are found.

● We demand that the cooling water flux should be 4-6L/min. Too high water flux may cause non-stabilization of laser spot due to its impact on the crystal. Too low water flux may cause accelerated aging of LD arrays or shortened lifetime of DPL due to insufficient cooling.

●  Each DPL has optimum working temperature of cooling water, please set the temperature of the chiller within +2ºC of the optimum temperature, and the control accuracy of water temperature should be within +1ºC.

3.Power Supply

If you use the power supply equipped by our company, please do not connect or disconnect DPL when the power supply is at the status of startup; if you want to use the power supply made by another company or yourself, please contact our company to confirm if it can be used.

●  After uncovering the protective covers on two output windows of DPL, check to see if there is blemish on two ends of the YAG rod, operation cannot be continued unless two ends of the YAG rod are clean.

●  Fix the DPL module on a plane and assemble the resonant cavity designed by the user.

●  Connect water pipes of the chiller to the water outlet / inlet of the DPL module. (The water outlet and water inlet can be exchanged.)

●  Connect the power supply to the DPL module (Connectors: red: + / black: -).

●  Adjust the resonant cavity in the user’s optional mode.

●  Turn on the power supply of the chiller (check to see if there is no water or no adequate water in the chiller), the water flux should be higher than 4L/min; Set the water temperature at desired value. (Each DPL module has recommended water temperature.)

●  Check the water outlet / inlet of the DPL module to make sure that cooling water can flow fluently and without water leakage, then quickly turn on the power supply and adjust working current to no less than 5A, because high humidity or large difference of the temperature inside the module and outside the module may cause dew on internal components, even make them failure.

●  Increase the current, but not higher than 20A. Normally the working current is about 18A when the output power is 50W. Water temperature should be set at 19-23ºC.

● When finishing using this product, quickly stop running the chiller to prevent dewing on internal components. Reduce the current to zero or press the power-cut triggered switch of the laser power supply, to quickly decrease the voltage of the chiller to zero, then other operation can be continued.
