Spectra-Physics Releases New Broadband Optics for CW Ti:Sapphire Laser

Mountain View, CA -- Spectra-Physics has released new broadband optics that enable their 3900S CW Ti:sapphire laser to be continuously tuned from 700 to 1000 nm. This offers a new level of convenience to 3900S users, since it previously required three separate sets of cavity optics to cover this range. For users who wish to operate at the edges of the 3900S spectral range, the company also offers extended blue and extended red mirrors sets to maximize the output power at these wavelengths.

The 3900S is the only commercial Ti:sapphire laser offering high performance continuous wave output, tunable from 690 nm to 1100 nm. This unique laser provides a robust, economical source of tunable red and near-infrared laser at output powers up to 2.5 watts. Wavelength is controlled by a single birefringent filter, which delivers an output linewidth of 40 GHz. For narrow line applications, the output linewidth can be further narrowed using optional etalons. These new broadband optics eliminate downtime for optics replacement and re-alignment, and will be particularly useful in research applications or where the laser is used as a shared resource.

A complete laser system includes the 3900S laser and a green laser pump source, such as the Spectra-Physics Millennia™ laser. Applications for the 3900S include IR Raman spectroscopy, "optical tweezers" for microscopic manipulation, and spectroscopy of semiconductor materials.
