At present, BrandNew can realize the full wavelength lock of the module from the threshold current to the working current, the wavelength current drift coefficient after lock is 0.015-0.02nm/A, and the spectral width is <1nm. This locking feature ensures that the center wavelength and line width of the semiconductor laser pump source remain unchanged during the startup and debugging of the device, and the product is not affected by the ambient temperature, which brings many advantages to the application.
Since the BrandNew module can achieve good wavelength locking near the threshold current, in the application of double-ended pumped solid-state lasers, it avoids the common front and back caused by the wavelength being unlocked and not absorbed by the crystal under the power-on or low current working conditions. The irreversible damage caused by the two-way pump source module pairing provides a good double-ended pump solution for high-power solid-state lasers. At the same time, due to the full wavelength locking feature, the BrandNew module can achieve continuous adjustment of zero to full power while the wavelength remains locked, which provides more convenience for terminal precision processing applications.
878.6nm 200/400/600μm core diameter output power 40W-175W, spectral width <0.5nm, and can achieve ±0.5nm wavelength locking (VBG)
The product has the characteristics of long life, high conversion efficiency, small size, stable performance, etc. After nearly two years of demonstration and verification at customers, the product performance is stable and reliable, and the light-to-light conversion efficiency is high. It uses self-developed and mass-produced single-tube chips , Excellent wavelength control and obvious advantages of high cost performance. It is an ideal pump source for solid-state lasers and solid-state picosecond lasers.
