Extensive use of electronic devices and development, will inevitably lead them around the space in its electromagnetic fields generated by the increasing level. In other words, the electronic equipment is inevitable in the electromagnetic environment. Thus, the solution of electronic equipment in the electromagnetic environment to adapt more and more attention. EMC Research central issue is how to control and eliminate electromagnetic interference to electronic equipment or system when linked with other equipment, does not cause equipment or any part of the system performance deterioration or reduced. Electromagnetic compatibility is the key technology to effectively control electromagnetic interference. Electromagnetic interference suppression technology is an important issue in the field of electromagnetic compatibility, electromagnetic interference suppression in many ways, electromagnetic shielding is one of the very important technology. People should purchase a  green laser pointer  with good anti-interference property.
Since the energy coupling through the front door may be the system of barrier protection devices will not interfere with or disrupt the system, and the system apertures is inevitable, therefore, coupled through the back door into the system, and system interference or damage to the device is a high-power microwave energy into the target system is one important way.
Electromagnetic shielding of electronic systems into the main two ways, first through the system of antennas coupled into the system, the so-called "front door" coupling; the second is by a system of holes and cracks, etc. into the system, the so-called "back door" coupling .

The operating time of green laser pointer can meet requirements of the customer

LD end-pumped solid-state ultraviolet laser to laser beam is focused to the nonlinear crystal acceptance angle range, as much as possible to reduce the impact of phase mismatch, which requires focusing not too tight. But this has affected the fundamental laser power density, thereby affecting the efficiency and frequency of light. In practice, these two factors must be weighed against the light output power and frequency of the highest. Based on the above analysis of experimental apparatus, designed the experimental setup shown in Figure 1. Maximum absorption of pump power of 600 mW. The use of C r4 +: YA G saturable absorber as passive Q-components. The operating time of  green laser pointer  can meet requirements of the customer.
Two end-plated 1 064 nm and 532 nm double antireflective film of the KT P doubling crystal placed in the right lens, a focal point, doubling the frequency of light at 532 nm 1 064 nm fundamental laser has been focusing lens 2 to the LBO crystal at the density. The fundamental frequency of the quartz prism light and ultraviolet light and frequency separated. In the choice of nonlinear crystal, we consider that in addition to frequency and frequency efficiency or efficiency as high as possible, but also the stability of the laser focus. 1 064 nm band in the cavity frequency doubling produced 532 nm green laser output, frequency-doubling crystal for the KT P the best crystal, phase matching type, the effective nonlinear coefficient, walk-off angle is small, so the conversion efficiency. Although KT P anti-damage threshold is low, but for low-power laser is not affected. The customer is satisfied with the normal operation of     green laser pointer      .
Taking into account the impact of birefringence of the SHG efficiency, we choose KT P length of 10 mm, less than its effective length 13.6 [8] IR LD pulsed lasers used in semiconductor production for the Chinese Academy of Sciences, the center wavelength of emission 808 nm, maximum output power of 1 W. LD pump light emitted through the optical coupling system of quasi-straight, round, focus, and ultimately become the ellipticity 019, waist radius, so the frequency-doubling crystal does not require temperature control, job stability. And frequency of the process we use is the LBO crystal, = 25 K [9] The other end coated antireflective film 355 nm. We choose the focusing lens of focal length 110 mm, both to ensure the harmonic beam quality, ensuring the efficiency and frequency conversion process, and ensures the fundamental frequency of light power. The normal operation of    usa green laser pointer       is in the process.
Because KT P crystal to accept relatively large temperature range, wide angle, acceptance wavelength range, and therefore more suitable for frequency. We choose the length of LBO crystal is 15 mm. Also do not need temperature control system. With a bandwidth of 300 MH z L eC roy 9631C digital display width of 1714 ns. Its frequency is 1617 kH z, the peak power of 240 W. Figure 3 shows the output characteristics of harmonic maps, in which the pulse width is 1412 ns, peak power of 25 W. Limitation is not due to equipment Figure 2 1 064 nm infrared pulse output waveform F ig. 2 T he figu re of the 1 064 nm pu lse la ser were infrared light filter harmonic Q-output characteristics of the laser pulse was measured (Figure 2, below). Among them, the abscissa is 3 times the vertical axis is the optical signal converted by the photodiode signal voltage V formation of values. The design of     green laser pointer       is at the world’s level.
Figure 2 is a 1 064 nm infrared laser pulse output characteristics map, can be seen from the figure-infrared laser pulses in Figure 3 532 nm second harmonic pulse output waveform measured UV pulse output characteristics map. Produced with Coheren t L abM a ster U lt im a P 540 power meter, LM 2 V 2 U UV detector measured UV laser pulse, the average power of 106 ∧. W Because infrared light pulse of light with frequency difference of 312 ns. The UV light pulse width and frequency difference will be less than this value, we take the UV pulse duration of 10 ns, can calculate the UV peak power of about 635 mW. The customer pays much attention to the design of     green laser pointer      .
