Laser Marking

The GFP is used as the laser’s “gain medium”, where light amplification takes place. The cells were then placed between two tiny mirrors, just 20 millionths of a meter across, which acted as the “laser cavity” in which light could bounce many times through the cell. Upon bathing the cell with blue light, it could be seen to emit directed and intense green laser light. Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. Gould’s notes included possible applications for a laser, such as spectrometry, interferometry, radar, and nuclear fusion.

The customer can preset the cleaning mode through the software, and can directly switch the mode for operation without adjusting the parameters, and start the cleaning without chemical reagent, medium, dust and water. Through auto focusing , surface fitting cleaning , removing resin, stain, rust, coating, paint, etc, the cleanliness is high. By now you already know that, whatever you are looking for, you’re sure to find it on AliExpress.

At high flux, the laser energy converts the rust or other unwanted material to plasma. Both low and high flux get the job done, but their use depends on the type of surface in question. Customer selected depending on the thickness of the material to de-rust.

In the case of extremely short pulses, that implies lasing over a considerable bandwidth, quite contrary to the very narrow bandwidths typical of CW lasers. The lasing medium in some dye lasers and vibronic solid-state lasers produces optical gain over a wide bandwidth, making a laser possible which can thus generate pulses of light as short as a few femtoseconds (10−15 s). Other applications rely on the peak pulse power , especially in order to obtain nonlinear optical effects.

The cavity converts the low-quality diode light into single-mode laser light. One of the fiber Bragg gratings acts as a total reflector, while the other serves as a partial reflector or output coupler. The solid-state architecture of fiber lasers makes them insusceptible to environmental factors such as dust, moisture, and free-space air perturbations.

Also known as dry ice blasting, cold jetting has similar characteristics to abrasive blasting, but without the problems of abrasive material recovery and disposal. While the cleaning is easy and effective, cost lies in the collection and disposal of the blast media, which often has to be separated from the paint debris, which has its own treatment issues. 2.precise cleaning, can achieve precise location, the exact size of the selective cleaning.

The damage brought by MOPA fiber laser cleaning is very small, and the roughness value is close or even lower than the original surface . While cleaned by CW lasers, the roughness value will be 1.5X more than the original surface. For pulsed fiber lasers, a laser with lower frequency is more likely to hurt the substrate during the cleaning process, and a laser with a narrow pulse width could clean the paint more easily. It’s essential to balance the heat between cleaning the paint and melting the substrate . A pulsed fiber laser with a master oscillator power amplifier structure offers the advantage of precise heat control, which is a critical point during the cleaning process.
