“…Optical rectification (OR) is a second-order nonlinear optical process that is responsible for the generation of DC polarization in nonlinear media. This process has been used in many recent reports to convert light directly into DC voltage [1,2,3,4,5,6]. The ultrafast response time of the second-order nonlinear OR and its broadband response spectrum at optical frequencies make it a good candidate for the development of next generation energy conversion devices [7] that can overcome present limitations of semiconductor photovoltaic cells.…”

A current challenge in photonics is to design new versatile photodetectors based on optical rectification induced photo-voltage; these ones are more attractive than classical photodetectors because they do not rely on band to band transitions. Identification of the origin of the photovoltage detected under intense illumination can sometimes be confusing due to the competition between several nonlinear processes. Examples of such processes are optical rectification, multiphoton absorption, and photothermal heating, all of which may result in the detection of a DC photovoltage in a capacitor configuration. Herein, differences between the resulting photovoltage from these processes are analyzed, and techniques are proposed to distinguish between optical rectification-induced DCphotovoltage and the photovoltage resulting from alternative effects.

“…One of the first experimentally revealed nonlinear optical effects is that of optical rectification (OR) -when a sufficiently powerful laser pulse passes through a nonlinear optical crystal, a dielectric polarization is formed in it, and the shape reproduces the envelope of the laser pulse [4][5][6][7]. For ultrashort pulses, such an effect is also known as difference frequency generation (DFG), in which subtraction of the frequencies at the edges of the femtosecond pulse spectrum occurs providing radiation in the THz range:…”

“…The circuit of the capacitor limits the spectral range of the detected signal, which is well below the THz range observed in the DFG, with the maximum voltage at zero frequency. Then the classical OR is observed, and the OR parameters (nonlinear susceptibility for OR, linear electro-optic coefficient [5], and efficiency of conversion of optical excitation to electric voltage [6]) can be determined with sufficient accuracy by measuring the voltage on the electrodes within the optical pulse duration. The measured voltage linearly depends on the nonlinear polarization.…”

The effect of optical rectification (OR) in the terahertz range (THz rectification, TR) is experimentally demonstrated. The effect consists of generating a DC voltage on the faces of a ferroelectric triglycine sulfate (TGS) single crystal under the action of pulsed radiation with a frequency of 1.57 and 1.96 THz and an electric field strength per pulse of 1.3 and 1.5 MV/m, respectively. The FLARE FELIX free-electron laser system (Radboud University, The Netherlands) was used as a THz radiation source. The TR effect makes it possible to directly determine the nonlinear susceptibilities of media (including those under conditions of strong absorption) without any reference or optical channel calibration and also without the need of Fourier transform.

“…To measure the parameters of pulse laser radiation, devices based on the optical rectification effect (ORE) in nonlinear optical crystals are also used [4,5]. The essence of the ORE lies in that, when high-power pulse laser radiation is transmitted through a nonlinear optical crystal, a nonlinear dielectric polarization is produced in it.…”

“…The relaxation time of the electron polarizability responsible for the ORE is ~10 -15 s [5]. Therefore, the time resolution of sensors based on the ORE exceeds the capabilities of all presently available PDs.…”

A Nanographite Film-Based Fast Response Detector for Intense Laser Radiation

A simple high-speed photodetector of high-power laser radiation, based on the optical rectification effect, is described. It operates without an external power source. A nanographite film deposited onto a silicon substrate using the plasmochemical deposition technique and having two conducting surface electrodes is used as the photodetector's photosensitive element. The performance of this device was demonstrated by detecting pulsed laser radiation in a spectral range of 0.266-1.9 µ m using the second, third, and fourth harmonics of radiation from an YAG : Nd 3+ laser with passive Q -switching and radiation from light oscillators based on stimulated Raman scattering in compressed hydrogen. It was shown that the photodetector sensitivity is proportional to the optical radiation frequency and its response time is shorter than 0.5 ns.
