Semiconductor laser pump sources, especially those with a wavelength of 969nm, have become the preferred choice for high-power/high peak energy disc lasers due to their reduced quantum losses and heat generation.

The 3000W 969nm fiber coupled semiconductor laser system launched by BWT uses 800 μ m NA0.22 fiber to output flat top optical energy distribution, combining lightweight and excellent optical performance, and can be widely used in scientific research and other fields.

In terms of design, BWT combines six 500 watt modules to achieve a 3000W power output scheme (as shown in the figure below). By adopting CTC chip integration technology, the system has the characteristics of miniaturization and lightweight, with a total size of only 80 * 482 * 521mm ³, a weight of only 24kg, and equipped with QBH output.

The system can achieve an output power of 300-3000W within the current range of 5-30A, with a center wavelength of 969nm and a side mode suppression ratio of over 25dB; When the power reaches 3000W, the edge mode suppression ratio is about 40dB, and the full width at half maximum of the spectrum is less than 0.3nm. To achieve a near flat top distribution of fiber output energy, BWT uses special techniques to improve energy uniformity, and the measured data shows a super Gaussian order greater than 4 (as shown in the figure below).

At present, BWT has a full range of semiconductor laser products (380nm-1940nm, 2mW-6kW), with laser pump sources covering the full power range of 10W to 1000W in the 8XXnm and 9XXnm series. In the future, we will launch higher power semiconductor laser systems to meet the demand of disc lasers for amplifying and outputting higher pulse energy in ultrafast lasers.
