Options

Narrow linewidth	With this option DL pro laser systems are optimized for narrow linewidths. It is also suited for seed lasers of TA or NLO systems as well as lasers of Laser Rack Systems but not for DL pro HP lasers. DL pro F lasers are always optimized for a narrow linewidth.
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.
Optical Isolation	Isolators are used to protect the laser diode against back reflections. This not only prevents damage to the diode but also ensures untroubled tuning and single-frequency operation. Fiber-coupling with angle-polished fibers (both ends) requires at least a single-stage isolator (> 30 dB). 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 (> 60 dB).
Beam Shaping	To shape elliptical laser beams into round profiles, either an anamorphic prism pair (APP) or cylindrical lenses are used. The compression ratio is set at the factory.
Motorization	The motorization of the coarse tuning offers manual control and operation via software interface. This option is available for most DL pro laser systems (most AR laser diodes and some FP diodes) including DL pro HP laser systems but not for DL pro F systems. See Downloads section below.
Bias-T	The DL pro (HP) has two modulation inputs that allow current modulation frequencies of up to 150 MHz. A Bias-T allows even higher current modulation frequencies of up to several GHz, depending on the diode. It is also suited for seed lasers of TA or NLO systems. This option is not available for DL pro F systems.
Electronics Modules	A broad variety of electronic locking modules is available for frequency stabilization.
