DL 100
Economic tunable diode laser
Economic, tunable cw diode laser
Widest wavelength selection: 370 nm .. 1770 nm
Output powers up to 300 mW
Modular design with hands-on set-up
TOPTICA’s DL 100 is a well-established and economic laser source for spectroscopy and many other scientific applications. It is an open system that can be changed and maintained by the experienced user. The DL 100’s specifications depend strongly on the implemented laser diode and are given in TOPTICA’s laser diode stock lists.
Applications

Options
DL-Mod
The PCB includes a FET and a Bias-T. The FET is DC coupled with an electrical bandwidth (-3 dB) of 20 MHz. The Bias-T is AC-coupled with an electrical bandwidth of > 300 MHz. The optical modulation bandwidths are generally lower and depend on the properties of the diode
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.
APP C
The compact prism pair is used for beam compression only. The compressed circular beam is small enough for using inexpensive small aperture isolators, and the fiber coupling efficiency is enhanced by approximately 10 %. The compression ratio is set at the factory. The variable APP J is available for beam compression and expansion.
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
A large range of control, stabilization and frequency locking modules are available.
