Femtosecond lasers have significant advantages for pulsed laser deposition applications. Due to the high peak power and short pulse duration, femtosecond laser pulses result in clean ablation with minimal thermal damage, shock-affected-zone, debris, or recast. The unique physics behind this athermal ablation (also called “cold ablation”) are described in numerous publications and also in the IMRA technical Notes section. This ablation process can be used as the first step for laser deposition and also is the basis for better results in terms of generation of particles and coatings. Here, we outline some specific examples of pulsed laser deposition applications which touch a number of important technology areas as diverse as electronics and automotive.
Products & Services
Dye lasers use a dye solution as an active medium. Their output is a short pulse of broad spectrum content with a high achievable gain.
Laser marking equipment uses a high-powered laser to mark or scribe materials with text, images, patterns, and graduations.
Nitrogen lasers are an excellent source of high intensity, short pulse, ultraviolet radiation. They can be used as an excitation source, or as a pump for a dye laser.
Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation.
Q-switches are devices used in the optical resonator of a laser to prevent lasing action until a high level of inversion is achieved in the lasing medium.
