CTL
Continuously Tunable Laser
- Wide mode-hop-free tuning (up to 130 nm)
- Available at wavelengths between 750 nm and 1750 nm
- High resolution (down to kHz level)
- Perform measurements at the (quantum) limit with low noise & drift (linewidth < 1 kHz)
- User friendly control panel and remote control
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). DLC CTL 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 CTLs exceptional properties. CTL includes an optical isolator that meets its specifications across the full tuning range without realignment.
