Skylark NX-Q
Compact turn-key DPSS laser modules driving quantum innovation
The Skylark NX-Q turn-key quantum laser modules simplify your work by handling everything from intensity modulation to frequency shifting, and absolute referencing.
Available in two wavelength ranges, 770 - 930 nm (NIR) and 390 - 450 nm (Blue MOT), we offer preset wavelengths tailored to your needs.
Ultra-narrow linewidth, ultra-low noise performance and the highest power within a compact form factor — the absolute reference for your quantum applications.
Miniaturised DPSS lasers designed for precise atomic control
Absolute referencing
Absolute referencing to external or on-board spectroscopic samples — providing an integrated solution to achieve long-term frequency stability.
Frequency modulation
A fast frequency modulator can be attached to the laser head. The modulator can be used in an external locking circuit with a maximum modulation frequency of 40 MHz.
Intensity modulation
TTL-actuated intensity modulation is available for adjusting both the laser output as well as the modulation frequency. This feature can be used for pulse sequences in a multi-laser setup.
External locking control
High-speed digital servo loop which can be used with an externally generated error signal. The external error signal can also be fed straight into the locking electronics. The feedback signal should be amplified to between 5 and 50 V.
DPSS lasers vs. semiconductor lasers for quantum computing and sensing
Laser precision is essential for trapping atoms and manipulating quantum states. When comparing semiconductor lasers to single-frequency diode-pumped solid-state (DPSS) lasers, the differences in performance — especially in output power, ASE noise, and linewidth — are critical for maintaining long term accuracy and control over quantum states.
The figure below demonstrates the inherent linewidth and side mode suppression of typical laser diode vs. Skylark NX C-DPSS laser.
Why choose Skylark NX-Q DPSS lasers for quantum computing and sensing?
Low ASE noise for ultra-stable performance
Skylark NX-Q DPSS lasers are engineered to minimise spectral noise for cleaner, more stable signals vs. semiconductor lasers that suffer from Amplified Spontaneous Emission (ASE) noise that affects stability and precision.
Ultra-narrow linewidth for long term measurement precision
The extremely narrow linewidth of Skylark NX-Q DPSS lasers provide long coherence and precision over extended interactions with quantum states whereas semiconductor lasers typically have broader linewidths that limit their ability to maintain coherence.
Higher power and efficiency for demanding quantum applications
DPSS lasers deliver higher output power with superior efficiency, and can be scaled to higher powers while maintaining excellent beam quality and stability. This is crucial for applications such as optical lattices and optical tweezers, where higher power lasers are needed to trap and manipulate atoms or qubits effectively.
Cost-effective long-term lifespan
Engineered for thermal stability and designed to prevent component degradation, Skylark NX-Q DPSS lasers are more durable for long-term use, whereas semiconductor lasers are cheaper to purchase, but have shorter lifespans under high power operation.
