Diode lasers have become an essential component in various industrial electrical applications, including production lines, material processing, medical equipment, and communication systems. Diode lasers are relatively affordable and compact, making them ideal for small and mid-sized businesses needing flexible and high-performing lasers. Choosing the right diode laser can be overwhelming, especially for businesses that lack experience in the field. In this article, I’ll share valuable tips on selecting the right diode lasers products for your industrial electrical applications.

1. Know the application

Before investing in a diode laser, it’s crucial to define the exact industrial electrical application you intend to use the laser on. Understanding your intended application allows you to know the specific requirements such as wavelength, power output, beam quality, and modulation frequency.
Sample heading
For instance, medical applications such as skin resurfacing and hair removal require diode lasers in the 600-1200nm wavelength range, while industrial material processing applications such as cutting and welding require diode lasers in the 900-1070nm range.

2. Consider the laser’s power output

Power output is a crucial factor when selecting a diode laser for your application. The power output of diode lasers ranges from a few milliwatts to hundreds of watts. If your industrial electrical application requires a high-power output, you’ll need a laser that can provide enough juice to handle the task. High-power lasers may require additional cooling elements, such as water or air cooling to prevent overheating.
Another sample heading
On the other hand, low-power lasers are suitable for medical, cosmetic, and scientific research applications, where precision is more critical than power output.

3. Check the beam quality

Beam quality describes how precise the laser beam is in its coherence, uniformity, and stability. The beam quality of a diode laser influences the cutting or engraving precision in industrial material processing applications. Beam quality is measured by the M2 factor, which ranges from a perfect beam (M2=1) to low-quality beams (M2>10).
Sample heading 3
High-quality beams are essential for microfabrication, engraving, and cutting tasks, while low-quality beams are ideal for heating applications such as soldering.

4. Check the wavelength range

The wavelength range of a diode laser affects the efficiency and accuracy of industrial electrical applications. Lasers with shorter wavelengths, such as UV diode lasers, are ideal for lithography and sterilization applications. While lasers with longer wavelengths, such as infrared diode lasers, are suitable for cutting, welding, and drilling.
Sample heading 4
Wavelength range is a crucial factor to consider when applying laser power to materials, as the interaction of the laser light with specific materials changes with the wavelength.

5. Look into the cooling requirements

Diode lasers generate heat during operation, leading to performance degradation or failure when overheated. In industrial electrical applications, where lasers are in constant use, efficient cooling is crucial to reducing heat accumulation and preventing laser failure.
Sample heading 5
There are two cooling options for diode lasers – air-cooling and water-cooling. Air cooling is suitable for low to medium power lasers, while high power lasers require water cooling systems to prevent overheating.

Conclusion

Diode lasers are an essential tool in many industrial electrical applications, so it's vital to make informed decisions when selecting the right product for your project. Knowing your application, checking beam quality, considering the laser's wavelength, and checking the cooling requirements will go a long way in helping you make the right decision. Remember, buying from reputable providers will ensure that you get high-quality and reliable products that meet your laser needs.
