With the optional additional Optical Parametric Amplifier (OPA) stage, the source also features high peak power (100 W) and an energy of 4 µJ per pulse. This OPO source converts the input signal from a 2 μm pump laser into a tunable Mid-IR beam using a nonlinear crystal. Its single longitudinal mode output features a kHz repetition rate and a few tens of ns of pulse duration. One of the widely tunable OPO source’s main applications is LIDAR remote gas detection in the whole LWIR or MWIR spectral region – implemented in a LIDAR system and tested in the field, the source allowed to successfully detect different toxic gas at a distance of 300 m.

Littman-Metcalf Configuration; Center Wavelength 1310 to 1330 nm; Wavelength Span >100 nm; Energy ≥17 mW; Coherence Length >7 mmNTT Advanced Technology Corporation’s 200 kHz swept light source for OCT imaging is currently the highest speed swept-wavelength light source in the world. Emitting wavelengths in the 1.3 μm band, the swept light source is ideally suited for OCT-based examination of the coronary arteries.The device accelerates image acquisition and as a result reduces diagnosis time. This reduction in diagnosis time contributes to a great reduction of both the physical and the psychological impact on patients.The total system cost can be reduced because the load on the image processing system is reduced and the linear frequency sweeping enables easy calculation of the relationship between time and wavelength.The swept-wavelength light source with a KTN deflector is aiming at the usage in phase sensitive OCT systems (Doppler OCT and PS OCT: applications to new OCT diagnosis methods) because of its lower jitter than that of the more generally used MEMS-based light sources.Core building block of the wavelength swept light source is a laser with an external resonator, the so-called Littman-Metcalf configuration. By optimizing the laser with a highly efficient diffraction grating and KTN light deflectors into a compact structure, high-speed operation, a wider wavelength sweep span, and sufficient coherence length are realized.Key Features:High Speed (200 kHz Sweep Rate)Voltage-controlled Sweeping Formats (k-linear scan available)High Phase Stability (Low Trigger Jitter <78 ps)Coherence Length 7 mm at 200 kHz ScanHigh Reliability (No Moving Parts)Wavelength Sweep Span >100 nmAverage Light Output ≥17 mWApplications: OCT Imaging

Four wavelengths: 532 nm, 555 nm, 579 nm, 606 nm; pulse-by-pulse switchable with 2 kHz; Pulse Energy 20 µJ; Pulse Length <5 ns The diode-pumped solid-state laser TETRA emits very short laser pulses (< 5 ns) of high energy (up to 20 µJ) with four wavelengths in the visible range, which are particularly suitable for multispectral photoacoustic imaging. Using sophisticated technology, the TETRA laser can switch from pulse to pulse between these four wavelengths with a very high pulse repetition frequency of 2 kHz. Utilizing the Raman effect and the light of a 532 nm pump laser, the TETRA laser additionally generates the wavelengths 555 nm, 579 nm and 606 nm. A tunable optical filter separates the four wavelengths and routes one wavelength at a time to the optical output of the unit at a switching frequency of up to 2 kHz. This makes TETRA about ten times faster than tunable lasers based on OPOs (Optical Parametric Oscillators) – typical frequencies of such OPO systems range from 100 Hz to 200 Hz – while also being considerably more cost-effective. The wavelengths emitted by TETRA are well matched to the absorption curves of many blood components, making the laser particularly suitable for photoacoustic tomography in biomedicine. We have equipped TETRA with a number of features to meet the requirements of medical safety standards for use in clinical environments. For instance a fast, fault-tolerant shutter at the laser output interrupts the beam in the event of a fault in the shortest possible time in order to avoid any hazards to a patient.
