THz generation by difference frequency generation can be accomplished by many different laser systems. The most cost efficient and compact solution will be monolithic dual-colour lasers. Application of these lasers in THz metrology can suffer from se

Abstract A slotted Y‐branch laser diode that emits two spectral modes at a difference frequency of about 1 THz is investigated in the context of photonic based cw‐THz measurements. The beating frequency of the emitted laser light can be tuned by

We investigate and compare the intensity and polarization dynamics in a vertical-cavity surface-emitting laser (VCSEL) with a monolithically integrated, electrically controlled birefringence tuning mechanism. The influence of the bias current on the

The generation and detection of radiation in the THz frequency range can be achieved with many different electronic and photonic concepts. Among the many different photonic THz systems the most versatile are based on diode lasers. In this paper we

In this study we analyzed some hematologic parameters of 228 autologous blood donors at a cardiosurgic clinic. The standard schedule of drawing autologous blood at our clinic is 4 units whole blood (450 ml) and 1 unit plasma (750 ml) for a time of 5

The use of autologous blood in patients with organ transplantations is feasible only when the blood is stored in the frozen state, since the timing of the operation is not predictable. A 53 year-old patient with dilatative cardiomyopathy was selected
