CW TUNABLE LASERS BROCHURE CW TUNABLE LASERS FOR QUANTUM APPLICATIONS EXPERTISE. INNOVATION. RESULTS

WIDEST PORTFOLIO FOR QUANTUM APPLICATIONS Tunable Lasers, Tapered Amplifiers and Frequency Converters Photoreceivers and Electro-optical Modulators Vibration Control, Optomechanics and Optics Ultra-high vacuum (UHV) mass spectrometers, gauges and valves have been emerging as a promising integrated platform for a wide range of applications from theoretical quantum physics to applied science. Pumped with a CW laser, multiple entangled photon pairs can be generated via optical parametric oscillation. ON THE COVER Quantum entanglement is a physical phenomenon in which photon pairs are generated such...

Matisse® CW Tunable Ring Lasers The Spectra-Physics® Matisse series is a family of state-ofthe-art single frequency ultra-stable, narrow linewidth tunable ring lasers. The Matisse system has the industry’s highest output power, the narrowest external linewidth, the broadest tuning range. Out of Plane Ring Resonator The Out of Plane cavity design is a stable and more reliable configuration delivering years of worry free operation. All CW ring lasers support uni-directional propagation of light within the laser cavity. Most ring lasers utilize a thin intracavity waveplate which is easily damaged,...

Matisse Features Narrowest Linewidth The Matisse is available with three levels of frequency stabilization: Passive stabilization with phase lock loop, active stabilization with reference cell, and active stabilization with Pound-Drever-Hall locking for ultranarrow linewidths to <30 KHz (100 ms integration time). Mode-Hop-Free Tuning Superior mechanical stability, specially designed optical mounts, unique tuning methods, and the preferred Out of Plane cavity design of the Matisse C all contribute to the exceptional mode-hop-free scanning range of >50 GHz. In order to take this to the next level,...

Matisse Stability Electronic Laser Self Alignment (ELSA) The Beam Steering Mirror on the input of the Matisse is mounted on a Picomotor™ actuated mirror mount. The Picomotor actuator is the best technology on the market enabling “set and forget” alignment. To account for long term pump beam-walk, the output power of the Matisse is monitored and provides feedback for self-alignment. Matisse input beam-steering mirror. ELSA control GUI. Two Etalons The unique cavity design of the Matisse incorporates two etalons. The second etalon provides increased long term mode stability. This “thick etalon”...

Matisse Software Control Fully Automated Software Control The Matisse is controlled with an intuitive GUI allowing fully automated and easy operation. Functionality, such as wavelength selection, piezo scanning, and frequency locking are easily visualized with a pictorial schematic of the Matisse laser cavity. Other GUI windows display automated monitoring of beam alignment and laser performance. Screenshot of the Matisse Commander software. Automated Scan Stitching The Matisse can perform indefinitely long scans by stitching the 50 GHz scans together. An implemented software routine automatically...

Wavelength Extension – An automated all solid state solution With various configurations of the Matisse, WaveTrain® doubler, and MixTrain™ frequency mixer, Spectra-Physics offers an all solid state solution for wavelengths ranging from 206 nm to 4.5 µm. WaveTrain 2 is an advanced standalone device that provides simple frequency doubling of single frequency CW laser beams. With greater efficiency than traditional intra-cavity or extra-cavity methods, this product can be used to generate the second harmonic of the output of the Matisse. WaveTrain 2 optical schematic The MixTrain utilizes quasi-phase...

WaveTrain 2 Resonant Ring Frequency Doubler • Most efficient CW SHG available today • Highest output powers available • Fast response piezo control • Piezo mounted prism in triangular configuration leads to excellent beam pointing stability • Auto-locking loop in stabilization circuit • 206 nm to 800 nm output Patented DeltaConcept® Cavity Design The WaveTrain 2 utilizes a ring cavity to achieve harmonic efficiencies greater than 35%. Unlike conventional bow-tie cavities, WaveTrain 2 is based on a patented triangle-shaped cavity configuration called the DeltaConcept®, which allows the cavity...

WaveTrain 2 Stability Sealed Resonant Ring Cavity for Crystal Longevity The WaveTrain 2 resonant ring cavity is housed in a massive metal block and sealed with an O-ring and metal cover plate. Hygroscopic material inside of the housing protects against humidity. The doubling crystal is temperature stabilized and a closed loop purge unit is available and a closed loop purge unit is available. There is no need to remove the lid of the sealed cavity during adjustment. This prevents cavity misalignment that can occur with lid closure. Isolation Legs The WaveTrain 2 is mounted onto 3-point ceramic...
