DL pro
あらゆる原子とイオンを冷却・制御するための研究室スタンダード
DL proは、あらゆる原子およびイオンにおける研究室スタンダードです。量子実験および応用向けに、DL proはプラグアンドプレイ方式のレーザーを提供します。本システムは世界中の研究室や量子関連企業において長年にわたり実績を積み重ねてきました。主要な原子・イオンすべてに対応する波長が利用可能であり、線幅狭窄のための高速レーザーロックモジュール FALC pro の追加など、後からシステムをアップグレードすることも可能です。また 1台の DLC proレーザーコントローラーで最大4台のレーザーを操作可能です。

DL pro HP
高出力を必要とする原子やイオンに最適実績あるDL proの高出力バージョンは、特殊な共振器設計を採用し、可視光領域におけるレーザーダイオードからの高い出力を実現します。DL proと同様に、各種変調入力を備え、ファイバー結合やビーム整形などのオプション装備が可能です。DL pro HPは、高出力を必要とする原子・イオンのトラッピングおよび冷却アプリケーションに最適です。例えば、461nmのストロンチウム遷移は、光アイソレータ後でも400mW以上の出力で駆動可能です。

DL pro F
クロック遷移に対する優れたロック性能DL pro Fではロッキングがこれまで以上に高速化され、次世代量子技術の基盤を築きます。当社のDL proのFモデルは、2つのフィードバックチャネルを提供するキャビティ内EOMを搭載しています。1つは優れたロッキング性能を確保するための高速調整に、もう1つはロックの高堅牢性を保証するために使用されます。数ある応用例の一つとして、729 nmにおけるCa+クロック遷移の制御が挙げられ、キャリア周辺の位相ノイズを低減します。

DL pro SMC

Frequency noise density measurement of a DLC DL pro at 1260 nm; instantaneous linewidths on the order of 1 kHz can be achieved for several diodes.
  • 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.
