Hey there! As a supplier of laser picosecond machines, I often get asked about various technical aspects of these amazing devices. One question that pops up quite frequently is, "What is the beam divergence of a laser picosecond machine?" Well, let's dive right into it and break it down in simple terms.
First off, let's understand what a laser picosecond machine is. These machines are pretty cool because they use picosecond - pulsed lasers. A picosecond is an incredibly short period of time - one trillionth of a second! This ultra - short pulse duration allows the laser to deliver high - energy bursts to the target area, making it super effective for a variety of applications, like tattoo removal, skin rejuvenation, and treating pigmented lesions.
Now, let's talk about beam divergence. Beam divergence is basically how much a laser beam spreads out as it travels away from the laser source. You can think of it like a flashlight beam. When you're close to the wall with a flashlight, the beam is small and concentrated. But as you move the flashlight further away, the beam gets bigger and more spread out. The same thing happens with a laser beam, and beam divergence measures how fast this spreading occurs.
In the case of a laser picosecond machine, beam divergence is a crucial factor. Why? Well, for one, it affects the precision of the laser treatment. If the beam diverges too much, the energy of the laser will be spread over a larger area than intended. This can lead to less effective treatment, especially when you're dealing with small, targeted areas like a tiny tattoo or a specific pigmented spot on the skin.
On the other hand, a very low beam divergence means the laser beam can maintain its focus over a longer distance. This is great for applications where you need to treat deeper layers of the skin or work on larger areas without losing too much energy due to spreading.
The beam divergence of a laser picosecond machine is usually measured in milliradians (mrad). A smaller mrad value indicates less divergence, meaning the beam stays more focused as it travels. For example, a laser with a beam divergence of 1 mrad will spread out less compared to a laser with a beam divergence of 5 mrad.
The design of the laser picosecond machine plays a big role in determining its beam divergence. High - quality optics are essential. The lenses and mirrors inside the machine are carefully engineered to control the way the laser beam propagates. If the optics are of poor quality, the beam divergence can be higher than expected, which can negatively impact the performance of the machine.
Another factor is the type of laser used. Different wavelengths of lasers can have different beam divergence characteristics. For instance, our 755nm Picosecond Laser Machine and 1064nm 755nm 532nm Laser Picosecond Pico Sure Laser Tattoo Removal Laser Machine are designed to have optimal beam divergence for their specific applications. The 755nm laser is great for treating pigmented lesions on the skin, and its beam divergence is tuned to ensure precise and effective treatment.
When it comes to applications, understanding beam divergence is key. In tattoo removal, for example, a laser with low beam divergence can target the tattoo ink particles more accurately. The high - energy, focused beam can break down the ink into smaller particles, which are then naturally removed by the body's immune system. If the beam diverges too much, some of the laser energy will be wasted on the surrounding skin, and the tattoo removal process may take longer or be less effective.
In skin rejuvenation, a well - controlled beam divergence allows the laser to stimulate collagen production in the deeper layers of the skin without causing excessive damage to the surface. The laser energy can penetrate the skin at the right depth and with the right intensity, thanks to the proper beam divergence.
Now, at our company, we take beam divergence very seriously. We use the latest technology and high - quality components in our Laser Picosecond Machine to ensure optimal beam divergence. Our R & D team constantly works on improving the design of our machines to provide the best possible performance for our customers.


We understand that different customers may have different needs. Whether you're a small skincare clinic looking for a precise machine for treating individual clients or a large tattoo removal studio that needs a high - powered machine for heavy - duty use, we have the right solution for you. Our machines are designed to be user - friendly, reliable, and most importantly, effective.
If you're in the market for a laser picosecond machine, it's important to consider beam divergence as one of the key factors. Don't just look at the power of the laser or the price tag. A machine with the right beam divergence can make a huge difference in the quality of the treatment and the overall success of your business.
