This article explains how pumping Nd-doped DPSS lasers at longer wavelengths around 880–890 nm, instead of the traditional 808 nm, reduces quantum defect and thermal lensing, delivering higher efficiency, better beam quality, and improved power scaling for precision micromachining and advanced materials processing.

The article explains how using volume Bragg grating (VBG)‑based upper‑state pumping in DPSS lasers improves absorption efficiency, reduces thermal loading, and stabilizes wavelength, enabling higher output power, better beam quality, and more robust operation for demanding industrial and scientific applications.

The article describes how high-power laser diode modules efficiently pump thin-disk solid-state lasers, enabling high output powers, excellent beam quality, and reduced thermal lensing, making them ideal for industrial materials processing, micromachining, and other high-brightness applications where scalable, reliable laser performance is critical.
