Tunable Lasers
Tunable lasers are laser light sources designed to emit coherent light at large range of wavelengths. Simply put, this ability to “tune” wavelenghts makes these lasers particularly useful in many applications requiring great flexibility and performance optimization. As such, tunable lasers are commonly used for spectroscopy, interferometry, microscopy applications and writing of Holographic Optical Elements (HOE). More recently, we have seen their rise within quantum research.
We offer two types of tunable lasers; CW & Q-switched. All tunable lasers are based on OPO technology covering VIS – MIR wavelength ranges. Wavelength Opto-Electronic is the partner of HÜBNER Photonics and Cobolt brand of lasers for Singapore, Malaysia, and Thailand.
C-WAVE
The C-WAVE tunable laser is a widely tunable continuous wave (cw), single-frequency laser light source based on optical parametric oscillator (OPO) technology. It offers total computer-controlled emission tuning across the visible and near-infrared wavelength range.
- Wavelength coverage from 450 nm up to 3.5 µm
- Up to 250 nm gap-free tuning range in the visible
- Single frequency operation with < 500 kHz typical linewidth

Cobolt Odin™
The Cobolt Odin™ Series is an ultra-compact and industrial-grade mid-IR source based on a fully contained temperature tunable Optical Parametric Oscillator (OPO) with an integrated pump laser.
- Wavelength selectable 3,1 µm – 4,6 µm
- Standard wavelengths 3264 nm, 3431 nm, & 4330 nm
- Tunable up to 50 nm
- Up to 80 mW at 10 kHz
- Narrow bandwidth <0.3 nm
- Ultra-robust, hermetically sealed packages, proven reliable
| Product | Wavelength | Power |
| Cobolt Odin™ | 3264 nm* | > 80 mW @ 10 kHz |
| Cobolt Odin™ | 3431 nm* | > 80 mW @ 10 kHz |
| Cobolt Odin™ | 4330 nm* | > 60 mW @ 10 kHz |
Qu-T™
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 fine-tuned (mode-hop free) over 10s of GHz. The laser wavelength can actively be 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.
- Large wavelength flexibility and high output power
- Narrow linewidth (<50 kHz, 1 ms integration time)
- High spectral purity (SMSR >60 dB)
- Multi-nm gap-free coarse tuning (>4 nm)
- Fast fine tuning (mode-hop free >10 GHz, typ.)
- Wavelength locking to various external references
- Compact format with proven 24/7 reliability
| Centre Wavelength, e.g. | 707 nm | 780 nm | 813 nm |
| Coarse Tuning | >4 nm | >4 nm | >4 nm |
| Fine Tuning | >10 GHz | >10 GHz | >10 GHz |
| Linewidth (1 ms) | <50 kHz | <50 kHz | <50 kHz |
| Output power | >500 mW | >500 mW | >500 mW |
