Toptica Product Focus: Continuously Tunable Lasers

TOPTICA Tuesday 20170530 400x650 CTL

Wide mode-hop-free tuning is important for many exciting applications: for example resonant excitation of small structures like quantum dots and micro-cavities as well as molecular spectroscopy or components testing. TOPTICA is specialized in tunable diode lasers with excellent precision, reliability and ease-of-use.

For example, TOPTICA’s CTL – continuously tunable laser – enables mode-hop-free tuning of up to 110 nm at several central wavelengths. Wide scans can be performed with highest resolution and narrow linewidth, and CTL features high absolute and relative wavelength accuracy as well as high power.

In combination with its fully digital controller DLC pro, the CTL laser is easy to use and operate via touch-screen and knobs as well as via remote PC GUI and command language. The low noise and drift levels of the controller make the CTL series even more stable and lowest-noise.
