The CTL is the ultimate choice when looking for a laser that is widely and continuously tunable without any mode-hops. It has high power, a narrow linewidth and low drift. Scans can be performed with highest resolution. Mode-hops are prevented by an innovative opto-mechanical design (patent US9960569B2) together with an active feedback loop called SMILE (Single Mode Intelligent Loop Engine) that keeps the laser on the same mode at all times. With the fully digital, low noise and drift DLC pro controller, the CTL laser is easy to use and operate via touch-screen and knobs as well as via remote PC GUI and command language (Python SDK). Since firmware 2.0.3 (free updates available), DLC CTL now includes a test system for characterizing components or recording spectra.

CTL lasers are ideally suited for applications that require large mode-hop free tuning ranges, such as the resonant excitation of small structures like quantum dots and micro-cavities. Also molecular spectroscopy and component testing will benefit from CTL exceptional properties.
