Publikováno v: Laser Applications in Microelectronic and Optoelectronic Manufacturing (LAMOM) XXII.

For most micromachining applications, the laser focus has to be moved across the workpiece, either by steering the beam or by moving the workpiece. To maximize throughput, this movement should be as fast as possible. However, the required positioning

We performed high signal-to-noise ratio TPF imaging of mouse intestine with a laser system exhibiting 30 fs tunable within 800–1200 nm, 50 mW average power, based on a compact Yb-doped laser seeding a microstructured fiber.

Low noise laser system generating 26 fs pulse duration, 30 kW peak power, and tunability from 800 to 1200 nm for ultrafast spectroscopy and multiphoton microscopy

Autor: Felix Brunner, Kurt J. Weingarten, Hubert Ammann, Andreas Rohrbacher, Bojan Resan

Publikováno v: SPIE Proceedings.

We demonstrate a novel low noise, tunable, high-peak-power, ultrafast laser system based on a SESAM-modelocked, solid-state Yb tungstate laser plus spectral broadening via a microstructured fiber followed by pulse compression. The spectral selection,
