Power Attenuator LPA
The LPA power attenuator is a small motorized laser-power controller. Rotating an input waveplate adjusts attenuation over a software-controlled0.1–97%range. A distinctive mechanical design ensures repeatability and stability. S and P outputs separate;S exits sideways and is absorbed by a heatsink to avoid thermal/stress interference in the housing. Optics are customizable by wavelength. A control cable connects to the included Power_Control controller.

Jmwafer
Laser cutting is a precise, noncontact process widely used in advanced wafer-semiconductor manufacturing. A focused high-energy beam locally melts or vaporizes material through photothermal effects. Wavelength, power and pulse width are adjusted to material properties for optimal cuts. 晶沐光电 has its own laser-processing line with UV/ultrafast lasers, wafer infrared stealth-dicing and cleaving machines, infrared fiber cutting machines and other equipment for varied wafer-cutting needs.

Laser pump sources are the core energy input component of solid-state lasers and laser amplifiers, and their performance directly determines the output power, beam quality and service life of the entire laser system. In scenarios such as industrial processing, scientific research experiments and high-end equipment, improper pump source selection will not only result in substandard system performance, but also bring a series of problems such as rapid device degradation and high operation and maintenance costs. This article sorts out the core selection logic and key pitfalls of pump source procurement, and provides selection references based on mature, mass-produced high-reliability products to help purchasers efficiently screen suitable products.
