Product Applications
In order to distinguish the product brand, identify the product category, meter and so on, there will be various signs on cables Now most of the cable manufacturers use ink coding machine for coding. Ink coding has a large pollution to environment. Because ink consumption is huge, it results in high cost of use. It is understood that a medium-sized enterprise yearly purchases printing ink of about 400000-500000 yuan or even millions yuan. And with the improvement of industry requirements, ink coding has not met the requirements of the industry.
Nowadays, laser marking machine (alias: laser coding machine, laser coding machine) has gone into the cable industry. Lasers with outstanding advantages, can meet the needs of the industry about clear, durable and other marking requirements. SO laser marking machines have been widely popular the cable industry. That laser code jet machine is used in the cable industry means that the date, batch number, brand, serial number, two-dimensional code and other symbols of cable products can never be changed once marked on. It plays a greater role in anti-counterfeiting. It also means that can resist part of the fake and shoddy cable products, that prevents some illegal manufacturers can take advantage. The early investment cost of laser marking equipment will be a little higher, but it does not have any consumables, and the power consumption is relatively low. In the long run, the absolute benefits are great.

The difference between laser MOPA and Q modulation(2-2)
In addition to the above several application cases, there are still many different application differences between MOPA lasers and modulated Q lasers. Here, some typical application cases are listed, as follows:
Applicaiton | Q-switched laser | MOPA laser |
Stripping the surface of aluminium oxide sheet | The substrate is easily deformed and the shading is rough | The substrate is not deformed and the shading is fine |
Marking black on anodized aluminum | Can't do this | By setting parameters, it can mark different color shades of blackness |
Deeply engraving on metals | The shading is rough | The shading is fine |
Color marking on stainless steel | Defocus is needed, parameters are difficult to adjust, the effect is difficult to achieve | Can achieve it by adjusting pulse width and frequency |
PC, ABC and other plastics | The effect easily can turn yellow; touch feel is tough | The surface is smooth and can not turn yellow |
Plastic buttons painted by transparent paint | It's hard to totally clean. | It’s easy to clean and efficiency is good |
Electronic products, semiconductor, ITO precision processing | The pulse width is large, the energy is above big, which may damage to the substrate | The pulse width is adjustable, the light spot is small. The energy can be adjusted evenly. |
The above comparison shows that MOPA laser can replace Q-switched laser in many applications. MOPA lasers are better in some higher-end applications.
Why do MOPA lasers have advantages over Q-switched lasers? We will explain the parameters of the two lasers one by one.
The parameter indexes of MOPA laser and Q-switched laser are different.
Here we compare the parameters of the typical Q-switched laser on the market with the M6 series MOPA laser of Shenzhen JPT laser:
Laser technology | Q-switched Pulse | MOPA Pulse |
Modulation technology | Q-switch | Electric signals to modulate seed sources |
Pulse wave shape | Can't be modulated | Can be controlled by modulating electric signals |
Pulse width | Fixed at 100ns | Modifiable at 2ns-250ns |
Peak power | Low, can't be modulated | High, can be modulated |
Pulse frequency | 20-80Khz | 1-1000Khz |
The first pulse rising time | Long, can't be modulated | Short, can be modulated |
Through comparison, it can be seen that MOPA lasers can be adjusted in pulse width, pulse frequency, control waveform and other aspects. By different combination of parameter modulation, so that various effects for different materials can be achieved. If the user needs a specific model, he can also modulate the exclusive laser parameters and make a comprehensive laser application solution.
