Design of a low power semiconductor laser driving power supplyWith the semiconductor in communication, measurement and control, medical, integrated optics and other technical fields of wide application, its attention is also increasing, for the design of a high precision, reliable performance, economic, durable driving power has become our current most urgent problem, because of the semiconductor laser "delicate" characteristics, the use of power must be in the performance and quality of strict control. Transfer characteristics of semiconductor lasersAt a certain temperature, wh

What are the differences between the QCW, CW and PW working modes of laser source?Laser source is a device that transfers energy from an active medium to an output beam. The working mode of the laser source has an important impact on the performance and application of the laser source. In the operation of laser source, QCW (pulse modulation width), CW (continuous wave) and PW (pulse wave) are common operating modes.

Laser cutting machine equipment common faults and solutions1, boot without any response▶ Power fuse is burnt out: Replace the fuse.▶ Power input is normal: Check power input and make it normal.▶ Main power switch is damaged: Replace the main power switch.2, no laser output or very weak laser▶ Optical path offset: Carefully adjust the optical path.▶ Contaminated or damaged reflector lens: Clean or replace reflector lens.▶ Whether the focal length of the device is changed: readjust the focal length.▶ Focusing mirror is contaminated: Clean the focusing mirror.▶ Cooling water quality or temperatur

Technical Trends of Switching Power Supply AbroadSince the 1990s, the development of switching power supply has changed with each passing day. Many new fields and new requirements put forward newer and higher challenges to switching power supply. If we observe from the input and output window of a switching power supply, we can find that the input requirements have become more stringent, and products that do not meet the IEC1000-3-2 standard will be gradually eliminated; The output has derived many special application fields, and the difficulty of research and development has become greater.

Switch power output protection policyIn all switching power supply designs, protection against load and protection against power supply due to load failure is a very important aspect to be considered in the design. In the design of military products, a kind of work called failure mode and impact analysis is often required. In this work, each part of the circuit is assumed to be an open circuit fault and then a short circuit fault. In this case, analyze separately how each fault will affect the rest of the circuit.

Power supply circuit analysis of pulsed semiconductor laserPulsed semiconductor lasers have the advantages of high peak power and small size, and are widely used in the fields of laser ranging, lidar and free space laser communication.

　　Portable laser marking machine is a device that uses laser technology to marking, which is usually used to engrave text, patterns, logo on the surface of various objects. It has the feature of simple operation, flexible operation, good engraving effect, and is widely used in jewelry processing, crafts, mold processing, woodworking, leather processing, paper-cut engraving and other fields. So what is the conventional voltage of the portable laser etching machine?

Classification of switching power suppliesSwitching power supplies can be divided into AC/DC and DC/DC. As a secondary power supply, DC/DC converter has realized modularization, and the design technology and production process have been mature and standardized at home and abroad, and has been recognized by users. However, due to its own characteristics, the primary power AC/DC has encountered more complex technical problems and manufacturing problems in the process of modularization.

Laser power supply technician is an important member of the operation of equipment, but in the operation of laser power supply, will also encounter a variety of difficult problems, today our factory technicians summed up the following problems, and according to the problem one by one to solve the problem, these problems are very key, I hope to pay attention to.▲ Power failure: Because the laser power supply system, especially the high-power laser power supply system needs a lot of voltage, the power supply related problems will produce inconsistent output power, leading to catastrophic damage.

Various techniques for switching power supplies to reduce lossesThe efficiency of PWM switching power supply without special loss control technology is lower than that of switching power supply with loss control technology. For switching power supplies that have no problem with heat dissipation, such as some off-line power supplies, the efficiency may be satisfactory. But for portable power supplies and devices requiring small size, greater efficiency must be sought.
