Pulse on Demand: New Micro-Joule Fiber Laser @ 1030 nm

TOPTICA Photonics presents the new FemtoFiber vario, 1030, a versatile micro-joule fiber laser ideally suited for, micromachining, material processing and life sciences. With a center wavelength of 1030 nm, the laser offers 2 W of output power at a repetition rate of up to 1MHz and a pulse duration of less than 300 fs. The special features of this laser include variable pulse duration via GDD control, adjustable repetition rate down to pulse-on-demand, and its superior temporal and spatial beam quality.

How To Measure Thin, Parallel Optics

Measuring the surfaces of thin, parallel optics can be challenging. When optics are less than a few millimeters thick, their front and back surfaces are so close together that it is difficult for standard interferometry to tell them apart. Fortunately, the right metrology equipment makes it possible to distinguish the surfaces and characterize the quality of both in a single measurement, even if they are less than a millimeter thick.

Lithography equipment manufacturers: Laser power measurement helps you to improve productivity

Coat, develop and expose! These three basic steps of semiconductor lithography have enabled smaller and cost-effective electronic devices to be made. Lithography system manufacturers, the key players of this technology, are patterning the chips by using laser radiation which needs to be optically characterized in terms of its power and stability for the profitability of the entire process.
