Leukos Industrial fiber Laser Repair

Leukos Laser Swing is a laser with unique performance, which has played an important role in many experiments in scientific research, industry and other fields.

(I) Wavelength characteristics

The operating wavelength of the Swing laser is 1064nm, which belongs to the near-infrared band. In animal material processing, lasers with a wavelength of 1064nm can work well on a variety of metal and non-metal materials. For example, in the process of metal cutting and welding, lasers with this wavelength can be efficiently absorbed and applied by metal materials and converted into heat energy, thereby achieving precision processing of materials.

(II) Pulse characteristics

Pulse width: Its typical pulse width is 50ps (picoseconds). Picosecond short pulses have unique advantages in the field of material processing. In the process of material processing, short pulses can concentrate and release energy to a tiny area on the surface of the material in a very short time. Taking ultra-fine micromachining as an example, when manufacturing tiny electrode patterns in microelectronic devices, a pulse width of 50ps can accurately control the energy range and avoid thermal effects on the surrounding area, thereby achieving high-precision processing.

(III) Beam quality characteristics

Low timing preset: It has low timing characteristics, generally less than 20ns. This characteristic is crucial in the application of laser amplification seed sources. When used as a seed source, stable timing output can ensure the synchronization and stability of pulses during subsequent amplification. In high-power laser systems, if the seed source timing is about to increase, after multiple stages of amplification, the time distribution of the pulse will be interrupted, affecting the output performance of the entire system. The low timing of the swing laser can effectively avoid such problems and ensure that the amplified laser pulse has good time characteristics and stability.

(IV) Energy characteristics

Single pulse energy: The single pulse energy is greater than 200nJ. In material processing, the appropriate single pulse energy can meet the needs of different materials and processing technologies. For difficult-to-process materials, such as high-temperature heat-treated alloys, the corresponding single pulse energy can provide enough energy to melt or vaporize the material, thereby achieving the processing purpose. In the field of micromachining, by precisely controlling the single pulse energy, the material can be lifted layer by layer, thereby producing a fine microstructure.

2. Common error messages and troubleshooting

(I) Power-related errors

Power cannot start: When the power cannot start error occurs, first check whether the power connection cable is loose or damaged. Make sure that the power cord plug is firmly connected and there is no poor contact. If the line is abnormal, please further check whether the power switch is working properly.

(II) Abnormal laser output

Reduced laser output power: When the laser output power is found to be lower than the normal level (usually lower than 80% of the nominal power), first check whether the laser medium is normal. The laser medium is a device. Check whether the device has obvious bends, breakages or contamination. For the surface of the optical fiber, special equipment cleaning tools and solvents can be used for cleaning.

(III) Optical path related errors

Beam deflection: When a beam deflection error occurs, please check the position of the optical component. If the optical components such as reflectors and beam holders are not installed in time or are impacted by external forces, beam deflection may occur, resulting in a change in the direction of beam propagation. Please use a precise beam measuring instrument to readjust the angle and position of the optical component to ensure that the beam can accurately propagate along the direction of the front beam.

IV) Long-term maintenance and care

Regular performance calibration: Send the laser to a professional calibration agency or have the manufacturer's technicians perform performance calibration every year. The calibration content includes accurate calibration of parameters such as wavelength, power, pulse energy, and beam quality to ensure that the laser performance always meets factory standards and application requirements.

Technology upgrades and software updates: Pay attention to the technology upgrade information and software update versions released by the laser manufacturer. Timely technical upgrades of the laser can improve the performance and stability of the laser and add new functions. For software control systems, regularly update the software version, fix known software vulnerabilities, optimize the operation interface and control functions, and improve user experience and equipment reliability.
