In this article, He in the base frequency of particular interest to the laser and its harmonic pulse irradiation of the harmonic emission and photoionization. As described below, the fundamental frequency laser of He + almost non-ionizing. , The He + has a high ionization potential relative to the usually rare gas atoms with He can get a higher cut-off energy. However, due to the smaller ionization probability, the harmonic conversion efficiency is low. But by the 27th or 13th harmonic of the additional titanium sapphire laser is to contribute to the He + ionization and photon emission, or by two-color frequency mixing or secondary transitions to the 2p or 2s state. The goggle of cell phone jammer can prevent the customer being hurt by the strong and powerful laser beam light of the laser pointer.
Combination of laser and its harmonic 27 or 13 pulses, the harmonic and ionizing than only baseband laser enhanced 10 in the baseband by the numerical solution of time-dependent Schrodinger equation results obtained show that: orders of magnitude. In order to study the interaction of helium ions in the combination of pulse and harmonic pulse, we solve the Schrodinger equation containing the length specification: the electric field of the laser pulse E (t). We envision that the laser field is linearly polarized vibration direction of the Z-axis. Equation 1 is obtained by numerical integration of the Peaceman-Rachford method [13]. In order to prevent the reflection of the wave function in the grid boundary [14]. Normally, when the customer buy this kind of cell phone jammer , the manufacturer will ship the complete set of laser pointer for the handy and convenient use of the customer.
At each time step, the wave functions are multiplied by a cos1 / 8 factor of the mask function [14]. The laser electric field in the form as follows: FF (t) and FH (t), respectively, for the fundamental frequency of the laser and harmonic pulse laser pulse envelope frequency laser pulse envelope for the Gaussian pulse duration of 10 femtoseconds, ω-based the angular frequency, n is the harmonic frequency, φ is the relative phase. In the general calculation, we used the grid scale for the 125-250 atomic units, the radial wave function of the maximum number of 100-200. The grid spacing of 0.125 atomic units, each time step, a titanium sapphire laser optical cycle of 1/65536. If there is no special statement, the fundamental frequency of the laser frequency is 800nm. This amazing characteristic of the laser of cell phone jammer is the extremely pure color of the laser beam light.
Another, we found that the results are not sensitive to the phase, so below, we set the relative phase of zero.
