LASER LAMPS: XAP, XAPD, XFP, KAP and KFP Series

Heraeus is a world leader in xenon pulsed and krypton CW lamp manufacturing. Heraeus has been in the laser lamp business since 1978, and some of our personnel have more than 20 years' experience in the industry. We offer a vast range of standard products. We also provide a special service which can tailor-make lamps to specific OEM customer requirements.

All lamps are manufactured and assembled in-house, in ultra-modern premises. Even jigs, tools and test equipment are built on-site. Only the highest grade materials -- including quartz produced by the parent company -- are used in lamp production; stringent quality control procedures maintain these high standards at all times.

Still, there is no question of the company resting on its laurels. New lamps and ideas for improving production techniques are continually under evaluation by our own research and development department. This ongoing program will ensure that Heraeus remains at the forefront in the 21st century and beyond.

How It Works

A pulsed lamp converts stored energy into bursts of radiant energy in the ultraviolet (UV), visible and infrared (IR) regions of the electromagnetic spectrum. The electrical energy is often stored in a capacitor (although switched power supplies are increasingly being used) which supplies high current to the lamp over short periods of time. Optical output energy results from this current ionizing and exciting the gas in the lamp. By selection of circuit components, various combinations of pulse energy, pulse width and repetition rate can be achieved. For more on principles of design and operation, click HERE .

Components of a pulsed lamp

• Gas Fill -- most commonly Xenon or Krypton
• Anode and cathode -- designed to easily emit electrons yet minimize material deposits along bore of lamp envelope
• Glass-to-metal seal -- rod-seal type for greater reliability and consistency plus higher current and power handling capabilities
• Lamp envelope -- made of fused silica and its variants, with selection baWsed on spectral output requirements
• Terminations -- a variety of terminations are available
