Broadband RC chaotic oscillators
ICCSC'02. 1st IEEE International Conference on Circuits and Systems for Communications. Proceedings (IEEE Cat. No.02EX605), 2003Recent investigations show that wireless communication systems are a very promising application area of chaotic dynamics. At the same time synthesis of chaotic oscillators suitable for IC implementation and producing chaotic oscillations in the specified frequency band is a problem.

Detecting nonlinear oscillations in broadband signals
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2009A framework for detecting nonlinear oscillatory activity in broadband time series is presented. First, a narrow-band oscillatory mode is extracted from a broadband background. Second, it is tested whether the extracted mode is significantly different from linearly filtered noise, modeled as a linear stochastic process possibly passed through a static ...

17.8 fs broadband Kerr-lens mode-locked Yb:CALGO oscillator
Optics Letters, 2021Pulses as short as 17.8 fs with a spectral bandwidth of 145 nm and central wavelength of 1118 nm have been generated from a Kerr-lens mode-locked Yb:CALGO oscillator. The oscillator operating at an average power of 26 mW and a repetition rate of 95.9 MHz is pumped by a cost-effective single-mode fiber coupled laser diode emitting 800 mW at 976 nm.

GaAs Bipolar Broadband Oscillators
1991 21st European Microwave Conference, 1991The GaAs heterojunction bipolar transistor (HBT) has been investigated for use in oscillators due to its combination of low flicker noise and high frequency performance. The HBT characteristics in oscillators have been assessed by constructing both varactor tuned oscillators (VTO) and, for the first time, YIG tuned oscillators (YTO).

Broadband YIG Tuned FET Oscillators
8th European Microwave Conference, 1978, 1978The association of a Ga As Field Effect Transistors (FET) and a Single Crystal Ferrimagnetic Garnets (YIG) has brought about the realization of oscillators electronically tunable in very broad bands. This paper presents the theoretical conception and the first experimental results of two types of FET-YIG oscillators.

Broadband Negative Resistance Oscillator Circuits
1969 G-MTT International Microwave Symposium, 1969Negative resistance oscillators can perform various functions other than just fixed frequency oscillations. For example, the electronic tuning effect is commonly used to generate FM signals and the injection locking phenomenon can be utilized for FM amplification, limiting and demodulation.

Compact cavity dumped broadband laser oscillator
SPIE Proceedings, 2009ABSTRACT Recent development of optically-pumped semiconductor laser (OPSL) technology provide a Ti:sapphire pump source reducing cost and complexity while maintaining a high standard of performance and reliability. In this paper we report on the performance of a compact (930 x 330 x 170 mm³), cavity-dumped ultrafast Ti:Sapphire laser oscillator pumped ...
