• Software-controlled automated beam alignment for Dual Head models

Since 2002, Photonics Industries has pioneered multimode performance with the DM Series, setting industry standards for high-energy and high-power operation. These diode-pumped, Q-switched lasers are engineered into a compact, industrial-grade platform suitable for both 24/7 manufacturing and advanced research environments.  

The DM Series delivers unmatched versatility, offering high pulse energies of up to 200 mJ and power levels reaching 400 W. It is available across multiple wavelengths, including 532 nm (Nd:YAG), 527 nm (Nd:YLF), and 351 nm (Nd:YLF), to meet a wide range of requirements. 

System performance is underpinned by outstanding pulse-to-pulse stability and a highly integrated design that eliminates performance loss over long umbilicals. The laser head features built-in driver electronics, while the entire system is managed via a user-friendly software GUI over RS232 or Ethernet. Furthermore, the power supply is consolidated into an ultra-compact 2U rack-mounted unit. 

Reliability is a cornerstone of the DM Series, evidenced by a field-proven service call rate of less than 1% during warranty periods. Intelligent features such as Dynamic Pulse Energy Control (PEC), power monitoring, and auto-attenuation ensure that a precise pulse energy is maintained throughout the laser’s life. This robustness makes the series an ideal choice for demanding industrial applications like laser shock peening, water-jet assisted cutting, and semiconductor processing. 

For users requiring maximum throughput, Dual Head models utilise two fully independent resonators within a single unit to double the power and energy output. This configuration is further enhanced by patented Twin Pulse mode, which generates pulse pairs from a single trigger. This mode allows for user-programmable energy splitting and pulse separation down to 1 µs from a single head, or even sub-microsecond timing in Dual Head mode. 

A significant advancement in the range is the DM Long Pulse (LP) Series, which features pulse widths extended up to 300 ns. This extension is critical for applications requiring longer thermal interaction times, such as polymer welding, thermal annealing of thin films, and nanoparticle sintering. 

The DM Series continues to lead the market in efficiency and space-saving design, providing a simple yet rugged form factor for complex tasks. Whether pumping Ti:Sapphire amplifiers, powering high-speed PIV systems or processing materials, these systems provide the advanced performance required.
