# ultrafast laser applications

Ultrafast lasers become more reliable and are … Our library is the biggest of these that have literally hundreds of thousands of different products represented. Ultrafast laser spectroscopy is a spectroscopic technique that uses ultrashort pulse lasers for the study of dynamics on extremely short time scales (attoseconds to nanoseconds).Different methods are used to examine the dynamics of charge carriers, atoms, and molecules. It deals with all kinds of effects occurring in these lasers, but also with phenomena which can be investigated using ultrashort laser pulses. While the effect of dispersion is minimal for many types of laser systems, it is especially problematic in ultrafast laser applications. Due to the Heisenberg uncertainty principle, transform-limited ultrafast pulses reaching the lower limit of their pulse duration have a wide wavelength bandwidth (Figure 1). For optical fiber communications, the GVD is typically defined as the derivative with respect to wavelength instead of frequency and is usually specified with units of ps/(nm km). The inverse group velocity is known as first-order dispersion, and GVD is known as second-order dispersion. This concept provides a way to create high-energy ultrafast laser pulses, opening up many scientific applications followed by industrial applications. This is Sections 10.1 and 10.2 of the Laser Optics Resource Guide. eBook includes PDF, ePub and Kindle version. Ultrafast lasers can also be used to produce laser pulses with enormous peak powers and power densities. Our lasers are designed and qualified based on the most demanding laser processes, and are therefore suitable for a wide variety of applications such as micromachining, medical or scientific applications. Just as the group velocity is similar to spectral dispersion, in that both correspond to the first derivative of refractive index with wavelength or frequency, the GVD is used similarly to the partial dispersion as they are both second derivatives with respect to wavelength or frequency. Bessel shaped beams are especially used to generate in-volume-modifications in transparent materials, like glasses or sapphire, for cutting applications. She has co-authored patents relating to laser processing materials and presented technical papers internationally.

Somewhere between those wavelengths (at about 1.3μm), there is a zero-dispersion wavelength where GVD is zero. Most optical media exhibit positive dispersion, so long wavelengths transmitting through them will have a higher phase velocity than that of shorter wavelengths, elongating the pulse duration (Figure 5). As such, the global ultrafast laser market is projected to expand at an impressive CAGR of 14% through 2030. Femtosecond Lasers for Industrial and Medical Applications. Need to contact Edmund Optics?

Topics include: micromachining applications About the presenter: Norman Hodgson, Ph.D., is vice president for technology and advanced research at Coherent Inc. in Santa Clara, Calif. When light of multiple wavelengths travels through a material, it is common for the longer wavelength (low frequencies) to travel slightly faster than the shorter wavelengths due to a frequency (or wavelength) dependence of the group velocity.1 This causes a spectral variation of the phase of the wavefront in the same way that light travelling through a prism is broken into its component colors from spectral dispersion of the material.
