Blog Article
In the vast field of modern laser technology, fiber lasers have become the core equipment for many industrial and scientific research applications due to their many advantages such as high efficiency and stability. However, to fully realize the potential of fiber lasers, key supporting modulation systems are indispensable. Among them, the 1064nm high-power AOM (acousto-optic modulator), as a 5W power-resistant industrial-grade device, plays a pivotal role in the fiber laser supporting modulation system.
Magical principle of acoustic-optical interaction
The working principle of 1064nm high-power AOM is based on acoustic-optical interaction. Simply put, it uses the interaction between sound waves and light waves to modulate the intensity and frequency shift of the laser. When sound waves propagate in the medium, they cause the density of the medium to change periodically, thus forming a structure similar to a "phase grating". When the laser passes through this "grating", diffraction occurs, thereby achieving precise control of the laser intensity and frequency. This seemingly simple principle contains a complex and subtle physical process, which is also the basis for it to play a key role in fiber laser modulation.
5W power tolerance: industrial-grade strength
One of the most prominent features of the 1064nm high-power AOM is its 5W power tolerance, which provides a solid foundation for industrial-grade applications. In industrial production, laser processing often requires high-power laser output, such as metal cutting and welding. Ordinary modulation devices can hardly withstand such high power, while the 1064nm high-power AOM can stably withstand up to 5W high-power optical input (some fiber optic devices can be customized) with its special all-metal structure design, compact and sturdy sealed packaging structure and innovative packaging process. This high power tolerance not only ensures reliable operation in a high-power laser environment, but also greatly extends the service life of the device, reduces the risk of failure caused by power overload, and provides a strong guarantee for the continuity and stability of industrial production.
Excellent characteristics, casting a modulation tool
In addition to the high power tolerance characteristics, the 1064nm high-power AOM also has a series of excellent product characteristics. The short response time enables it to respond quickly to external control signals, and in applications that require rapid modulation of laser pulses, it can accurately control the output rhythm of the laser; low insertion loss means that the laser loses very little energy when passing through the modulator, ensuring efficient use of laser energy; high extinction ratio ensures that the modulated laser signal has good contrast, and the output laser signal is purer and more stable. In addition, high temperature stability and reliability as well as miniaturized design enable it to work stably in harsh industrial environments and be easily integrated into various compact fiber laser systems.
Its performance advantages can be seen more clearly from the specific parameter table. The specific values of different models in terms of insertion loss, rise time, frequency shift, etc. all show its outstanding performance in various performance indicators. For example, the rise time is as short as nanoseconds, the frequency shift range is optional and has sufficient bandwidth, all of which provide support for its precise modulation in practical applications.
Widely used, lighting up the future of laser
In practical applications, 1064nm high-power AOM has a wealth of application scenarios. In Q-switched fiber lasers, it can accurately control the pulse output of the laser and achieve high-energy, high-frequency laser pulses, which are widely used in industrial production links such as laser processing and laser marking; in laser Doppler coherence applications, by accurately modulating the laser frequency, it can achieve high-precision measurement of object speed, displacement and other parameters, playing an important role in scientific research experiments, industrial detection and other aspects; in applications such as ultrafast laser frequency reduction menus and linear frequency modulation, it can also provide stable and reliable modulation support for these advanced laser technologies with its excellent performance.
1064nm high-power AOM has become the core component of the fiber laser supporting modulation system with its unique principle, strong power resistance, excellent product characteristics and wide application fields. In the future, with the continuous development of laser technology, it will surely shine in more fields and contribute more to the advancement of laser technology. Report this page
