Pulsed Flash Lamp - Xenon and Krypton

Flash lamps

Heraeus has many years of experience in providing DC pulsed flash lamp (Xenon, Krypton) to leading solid-state laser manufacturers and non-laser applications like IPL or sun simulation. Heraeus flash lamps normally operate at high average powers with pulse duration from the millisecond regime and repetition rate up to many kilohertz. Heraeus lamps offer high efficiency, stability and long lifetimes.

Typical laser applications include precision cutting and drilling, spot welding and mould repair. Non-laser applications include hair removal, skin treatment, sun simulation and semiconductor processing. Heraeus work closely with our customers utilising our extensive internal and external research facilities and institutes to provide the industry with high quality flash lamps.

Pulsed Xenon Flash Lamp

The typical usage of Xenon flashlamps is as the pump source for Laser systems. The output spectrum of Xenon closely matches the absorption wavelengths of Nd:YAG and many other lasing materials. However the broadband spectrum, provides useable wavelengths from 160nm – 1000nm, making the xenon flashlamp a versatile light source for other application areas.

By altering the pulse shape, pulse duration, and current density its possible to maximize the output for many application areas. The envelope material can be customized to filter or enhance UV output, and can achieve the desired spectrum without harmful additives such as mercury or metal halides.

Heraeus can offer a wide range of standard flashlamp desgisn from an extensive cross reference list or offer a custom design service.

Pulsed Krypton Flash Lamp

Flashlamps can also be filled with Krypton gas, or sometimes a mixture of Krypton/Xenon. Krypton gas offers line radiation which matches the absorption spectrum of Nd:YAG, particularly at lower power densities (<16kWcm2) and is therefore better suited for some Laser applications.
At power densities >6kWcm2 Xenon becomes more efficient as the continuum radiation begins to dominate
