Compact Tunable Lasers – Single Frequency – Mode-hop Free Tuning
The Cobolt Qu-T™ Series offers tunable and lockable single-frequency CW emission in the 650-950 nm range with an inherently high level of flexibility in the center wavelength and a perfect TEM00 beam. Each emission wavelength can be coarsely tuned gap-free over several nm and actively locked to an external reference using a fast piezo control. Combined with such tunability and locking capability, low intensity noise and narrow linewidth emission make these lasers perfectly suited for quantum experiments based on atomic transitions and generation of entangled photon pairs through spontaneous parametric down-conversion.
Key Features:
- Large wavelength flexibility and high output power
- Narrow linewidth (<100 kHz free-running)
- High spectral purity (SMSR >60 dB)
- Multi-nm gap-free coarse tuning (>4 nm)
- Fast fine tuning (mode-hop free >5 GHz, typ.)
- Frequency locking to various external references
- Compact format with proven 24/7 reliability
Applications:
Quantum Research, Quantum Computing, Atom Cooling, Atom Clock Research, Raman spectroscopy
