SMSR Performance• 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

PRELIMINARY| J A N U A R Y 2024 | H U B N E R- P H O T O N I C S .CO M• Compact format with proven 24/7 reliability

The Cobolt Qu-T™ Series offers tunable and lockable single-frequency CWemission in the 650-950 nm range with an inherently high level of flexibility inthe 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 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.
Built into compact hermetically sealed packages using Cobolt HTCure™ manufacturing technology with proven 24/7 reliability, the Cobolt Qu-T™ lasers
provide robust performance over a wide range of operating conditions from asmall and easy-to-use platform, and can therefore also contribute to bringing
the most advanced quantum research set-ups into real world applications.
