This BWT vertical laser diode stack is engineered for applications demanding high power and exceptional stability. At its core, the stack leverages advanced microchannel cooling technology, providing highly efficient thermal management that is critical for maintaining wavelength precision and enabling a high duty cycle in continuous wave (CW) operations. This robust cooling allows the 6-bar array to deliver a powerful 360W at the industry-standard 808nm pumping wavelength.
Built for long-term operational life, the stack utilizes AuSn (gold-tin) hard solder packaging, which offers superior resistance to thermal fatigue compared to standard indium solders. This manufacturing quality, combined with a low “smile” characteristic, ensures superior beam quality and reliability, making this laser diode stack an ideal component for integration into industrial and medical systems.
As a high-brightness source, it is perfectly suited for OEM integration into solid-state laser pumping (DPSSL) systems, materials processing workstations, and high-power medical devices where consistent performance is paramount.

This diode stack can be customized for specific application needs. Parameters such as center wavelength, output power, and number of bars can be adjusted for volume orders. Please contact our engineering team with your specific requirements to discuss a custom or OEM solution.
The values presented in the specification table are typical performance figures measured under controlled laboratory conditions. All data is measured at a case temperature of 25°C. Performance may vary depending on the actual operating temperature, thermal interface, and driver stability.
This is a high-power Class 4 laser device. Avoid eye or skin exposure to direct or scattered radiation. All personnel entering the operating area must wear appropriate laser safety goggles rated for the 808nm wavelength range.
To prevent clogging and electro-corrosion, this microchannel cooler requires high-purity, deionized water with a conductivity of 2.5±0.5 µS/cm and a pH value between 5.5 and 8.0. The water must also be filtered to remove particles larger than 5µm.
You must provide a minimum water flow rate of ≥1.8 L/min to ensure adequate heat dissipation. The water pressure should be maintained at less than 5 Bar to avoid damaging the microchannel structure.
This is a high-power CW (Continuous Wave) device. You will need a specialized laser diode driver capable of supplying a constant current of up to 65A at a voltage of up to 12V. It is critical to use a stable, low-noise power supply to avoid current surges.
For compatible solutions, please explore our range of high-power laser diode drivers.
“Smile” is a measurement of the straightness of the laser-emitting bar on the diode stack. A “Low Smile” value indicates that the bar is very flat and straight, resulting in a more uniform beam. This is a key indicator of high manufacturing quality and leads to better performance.
Pair your diode with the right driver and temperature controller for stable, reliable performance.
