LZY pulsed semiconductor power supply

As the core light - emitting component of the optoelectronic system, semiconductor lasers have achieved full - industrial - chain coverage applications. Statistics show that their installed capacity in fields such as material processing (accounting for 35%), optical communication (28%), and medical equipment (18%) has an annual growth rate of over 15%. The conversion efficiency and control accuracy of the supporting drive power supply directly affect the key performance indicators of terminal devices.

In recent years, the technical penetration rate of semiconductor lasers has shown a cross - field growth trend. There are extensive application scenarios in key fields such as basic scientific research, advanced manufacturing, national defense technology, and biomedicine. As the core component for driving lasers, the performance of the laser power supply directly affects the stability, efficiency, and lifespan of the laser. With the increasingly widespread application of semiconductor lasers, the requirements for the corresponding drive power supplies are becoming more diverse. Laser power supplies with data processing, status monitoring, fault diagnosis, and output control capabilities have become the new development direction of semiconductor laser power supplies.

Why is RaySource's Pulsed Semiconductor Power Supply the First Choice in the Industrial Laser Field?

For many years, RaySource has focused on the development of laser power supply technology and has accumulated solid technical expertise over the years. It started researching and producing CO₂ laser power supplies in 2003. Semiconductor laser power supplies are one of the main products of RaySource Laser. In 2014, it entered the field of fiber semiconductor drive power supplies. In 2015, it successfully developed a continuous high - power fiber semiconductor drive power supply and cooperated with professional laser manufacturers, scientific research institutions, and military units.

The core advantages of RaySource's semiconductor laser power supplies lie in "technical accumulation, practical application, and high - efficiency reliability". They can meet the diverse needs of high - power lasers from industrial - grade to military - grade, and at the same time, help laser technology develop towards miniaturization and high - performance. Its technical barriers are mainly reflected in high - precision control algorithms, reliable protection algorithms, fault detection, judgment, and storage, high - frequency multi - topology circuit design, and multi - system integration capabilities.

Classification of Semiconductor Laser Power Supplies

Semiconductor laser power supplies are divided into pulsed semiconductor laser power supplies and continuous semiconductor/fiber laser power supplies.

Pulsed semiconductor laser power supplies are further divided into short - pulse semiconductor laser power supplies and long - pulse semiconductor laser power supplies. For short - pulse semiconductor laser power supplies, the pulse width is generally within 1000 μs, the repetition frequency is 1 - 5KHz, the current is 50 - 1000A, the voltage is 2 - 700V, and the average power of a single module is generally below 10KW. For long - pulse semiconductor laser power supplies, the pulse width is generally within 500ms, the repetition frequency is 1 - 100Hz, the current is 50 - 300A, the voltage is 2 - 100V, and the average power of a single module is generally below 20KW.

Continuous semiconductor/fiber laser power supplies are divided into two types: the MOPA structure with a seed source + 1 - 3 - stage amplification and single - stage direct output. The voltage and current of the amplification stage are generally below 200V/60A, but the number of channels can reach several hundred, corresponding to a power of several hundred kilowatts.

Composition and Functions of Semiconductor Laser Power Supplies

The circuit part of a semiconductor laser power supply consists of a voltage - stabilizing circuit, a current - stabilizing circuit, a digital control logic analysis and storage circuit, a detection circuit, a protection circuit, etc. Digital semiconductor laser power supplies use digital integrated circuits as the core to achieve intelligent control.

In addition to voltage and current stabilization, semiconductor laser power supplies also need to achieve current - source drive and protection, optical power feedback control, fault interlocking, fault protection, fault location, fault alarm and storage, remote control, constant - temperature control, display, and other functions.
