CTL
Continuously Tunable Laser
Mode-hop-free tuning up to 110 nm
Available at 950, 1050, 1320, 1470, 1500 and 1550 nm
Up to 80 mW output power
High resolution and wavelength accuracy
User friendly touch screen, buttons and remote control
The CTL is the ultimate choice when looking for a laser that is widely tunable without any mode-hopping. It has high power, a narrow linewidth and high absolute and relative wavelength accuracy. Wide scans can be performed with highest resolution. 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.
The new 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 components testing will benefit from CTLs exceptional properties.

Options
Optical isolation single stage
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.
Optical isolation double stage
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.
FiberDock
TOPTICA's patented fiber coupler provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability. TOPTICA additionally offers a wide range of single-mode and polarization maintaining fibers, including fiber-optic beam splitters. Optical isolation is mandatory for fiber coupled diode laser systems.
Electronics Modules
DLC pro LOCK laser stabilization option. In addition, a large range of control, stabilization and frequency locking modules are available with DLC ext
