  • Vitara Ultrafast Laser
Oct 2011
Coherent Inc.Request Info
SANTA CLARA, Calif., Oct. 24, 2011 — Vitara, from Coherent Inc., is a widely tunable ultrafast laser that delivers pulse widths shorter than 12 fs. It offers true hands-free and fully automated operation, including automated wavelength tuning over the 755- to 860-nm range and push-button bandwidth adjustment from 30 to 125 nm. The output power peaks at >450 mW because of the fully integrated and compact Verdi G 5-W pump laser, which is based on proprietary optically pumped semiconductor laser technology.

As with the company’s other one-box ultrafast lasers, it is designed to bring state-of-the-art performance to a variety of users. The 125-nm maximum bandwidth delivers a specified pulse width of <20 fs, with a typical pulse width of 15 fs directly from the laser output. The optional compact compressor enables the pulse width to be further compressed to 12 fs or less. Other options include a next-generation carrier envelope phase stabilization (CEP) module that delivers high phase stabilization, and a Synchrolock module for external pulse timing stabilization.

Applications include seeding short-pulse amplifiers and CEP-stabilized amplifiers, which benefit from Vitara’s stability and bandwidth, and pump probe spectroscopy where the short pulse width is an advantage. Others include terahertz spectroscopy and imaging, where the short pulse width produces a high terahertz bandwidth, multiphoton microscopy and multiplex coherent anti-Stokes Raman scattering imaging.
