Pulse-to-pulse relative intensity noise measurements for ultrafast lasers [PDF]
Optics Express, 2022 Relative intensity noise (RIN) can be used to characterize pulse-to-pulse energy variations of ultrafast lasers, and is a very important performance parameter when considering the suitability of a laser for an application. However, owing to a wide range of measurement and analysis techniques, comparison of RIN values is non-trivial.

Measurements of relative intensity noise (RIN) in semiconductor lasers [PDF]
Journal de Physique III, 1992 The intensity fluctuations of the laser diodes light are characterized by the so-called relative intensity noise (RIN). In this paper a very accurate measurement technique is presented and results are given on some components. RIN measurements on isolated longitudinal modes can explain how the energy is shared between the modes.

Measurement of the laser relative intensity noise [PDF]
2009 IEEE International Frequency Control Symposium Joint with the 22nd European Frequency and Time forum, 2009 This article describes the measurement of the RIN power spectral density with the cross-spectrum method. Averaging the cross spectrum of two equal and independent channels that measure the same beam, the instrument background is not limited by the single-channel noise.

Reduction of the Relative Intensity Noise of Broadband Sources Using Dual Fiber Ring Resonator
IEEE Photonics Journal, 2023 Interferometric fiber-optic gyroscopes (IFOGs) are widely utilized due to their compact size and solid-state design. However, their sensitivity of detecting rotation is limited by the relative intensity noise (RIN) associated with the broadband source ...

Intensity instability and correlation in amplified multimode wave mixing
Scientific Reports, 2022 The dynamics of optical nonlinearity in the presence of gain and feedback can be complex leading to chaos in certain regimes. Temporal, spectral, spatial, or polarization instability of optical fields can emerge from chaotic response of an optical $$\chi

Relative intensity noise suppression in reflective SOAs [PDF]
Optics Communications, 2014 Abstract The reflective semiconductor optical amplifier (RSOA) capability to compress the relative intensity noise (RIN) is well-known and widely exploited in wavelength division multiplexing passive optical networks (WDM PON). While this feature has been previously analysed using SOA theory, in this paper we show that RSOAs present specific gain ...
