CTL

Continuously tunable laser
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, and is available between 750 and 1750 nm. Scans can be performed with highest resolution. Mode-hops are prevented by an innovative opto-mechanical design together with an active feedback loop called SMILE (Single Mode Intelligent Loop Engine) that keeps the laser on the same mode at all times (patent US9960569B2). 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.

Your Benefits

Continuous tuning - continuous measurements
No mode hops across the full tuning range - up to 130nm. Just tell CTL a wavelength and it will tune there - or perform a linear scan from one wavelength to another - while recording spectra simultaneously. Don't miss a spectral feature like a quantum dot resonance or perform tedious scan stitching - just scan - and easily make the best measurements ever. 
Pick your wavelength
CTL is available between 750 nm and 1750 nm. Several CTL models are available, enabling mode-hop free tuning and measurements between 750 nm and 1750 nm. 

Applications

Photonic integrated circuit characterization
Quantum dots & microcavaties
Optical component testing
Sensing & spectroscopy

Options

Single stage optical isolation
Isolators are used to protect the laser diode from back reflections. This not only prevents damage to the diode but also ensures untroubled single-mode operation and tuning. Fiber coupling with angle polished fibers (both ends) requires at least a single stage isolator.
Dual stage optical isolation
Double stage isolators are needed if reflections from the experiment into the laser are expected. Fiber coupling with non-angle polished fibers also requires a double stage isolator.
Fiber delivery
Fiber Delivery (FD) is optionally available with TOPTICA's patented fiber coupler FiberDock and a suitable polarization maintaining (PM) fiber. FiberDock provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability. For most lasers, we specify a PER behind fiber of >20 dB with our Fiber Delivery option. Please also inquire about Long Life and High Power fibers as well as fiber splitters. Optical isolation is mandatory for fiber coupled diode laser systems.
Locking and other electronics modules
A broad variety of electronic locking modules is available for frequency stabilization.
Optical amplification
An optical amplifier, BoosTA pro, can be operated from the same DLC pro controller.
