The 808nm 3kW vertical laser diode stack is designed for high-peak-power, pulsed (QCW) laser applications where reliability and ease of cooling are paramount. It features a robust macro channel cooling architecture, which is less sensitive to water quality than microchannel designs and allows for the use of standard industrial water filters and even anti-freeze. This makes the stack an ideal choice for integration into demanding industrial and field-deployed systems.
The 20-bar array is optimized for the 808nm wavelength, making it a powerful energy source for solid-state laser pumping (Nd:YAG) and the gold standard for medical aesthetic applications like laser hair removal. With its multiple defined operating modes (High Peak, Short, and Long pulse), this stack offers the versatility needed for a range of industrial and scientific uses, all protected by an integrated glass cover for enhanced durability.

This stack has multiple defined operating modes (High Peak, Short, Long). Note that the “Expected Lifetime” is specified in **Mshots (millions of shots)** and varies depending on the pulse width and duty cycle used. All data is measured at a case temperature of 22°C.
Avoid eye or skin exposure to direct or scattered radiation. All personnel must wear appropriate laser safety goggles rated for the 808nm wavelength range when the device is active. The integrated glass cover provides protection for the laser facets but does not block the output beam.
The primary advantage is robustness. Macro channel cooling is significantly less sensitive to water quality than microchannel designs. It allows for the use of industrial-grade filtered water and is compatible with appropriate anti-freeze solutions, making it ideal for demanding environments where water purity cannot be guaranteed.
No. This is a **QCW (Quasi-Continuous Wave)** device and requires a dedicated pulsed laser diode driver. The driver must be capable of delivering high-current pulses (up to 160A) and providing precise control over pulse width (ms) and frequency (Hz) to match the specified operating modes.
The choice depends on the trade-off between pulse energy and device lifetime. The “High Peak” mode (5ms pulse) offers the longest lifetime at 30 million shots. The “Short” (20ms) and “Long” (100ms) modes deliver more energy per pulse but have a shorter expected lifetime of 15 million shots. Select the mode that best fits your application’s requirements.
“Mshots” stands for millions of shots (or pulses). Unlike CW lasers rated in hours, the life of a QCW laser is measured by the number of on/off cycles it can endure. A lifetime of 30 Mshots means the stack is expected to deliver 30 million pulses under the specified conditions before its output power drops by 20%.
The integrated glass window serves as a protective barrier for the laser diode facets. It shields the delicate emitting areas from dust, debris, and accidental contact during handling and system integration, significantly increasing the robustness and reliability of the stack in real-world operating conditions.
