The blue laser pointer will be more expensive than the green laser pointer

 The blue laser pointer will be more expensive than the green laser pointer.
This plasma can radiate rays of various wavelengths of laser. High-power femtosecond laser and electron-beam collisions can produce hard X-ray femtosecond laser, resulting in the β-ray laser to produce electron-positron pair. The use of femtosecond laser can be very effective to accelerate electrons, the size of the accelerator are compressed thousands of times. Have good prospects in the high-power femtosecond laser in medicine, ultra-fine micro-machining, high-density information storage and records. High-power femtosecond laser air breakdown, thereby creating a discharge channel, artificially triggered lightning, to avoid the catastrophic damage caused by aircraft, rocket, power plants due to natural lightning. High-power femtosecond laser interaction with matter.
Smart car rear-wheel drive, rear wheel with a motor-driven, relying on the corner angle of the steering gear modulation two wheels in the front so as to achieve the purpose of steering control, front-wheel-oriented wheel, at the same time starting a support role. Tracking laser head were installed in the body in front of two rows layout, wide track, the laser is divided into two parts, left and right side of black line detection, two-row arrangement of the laser head of a row of eight two rows of irradiation angle of each responsible for one side, when the body of the laser head to the left of the detected black lines, the steering gear of the car to accept the corner of the command to the right, when the laser head is detected black lines of the body the right car steering gear to accept the corner command to the left, so as to achieve the purpose of traveling by car along the black line [7]. It is on the production of laser pointer .
Period and pulse width can be double buffered. When the channel is turned off or PWM counter reaches 0:00, the change cycle and pulse width is applied. 8 bytes or 16 bytes of channel protocol. There are four clock sources are available (A, SA, B, SB), they provide a wide range of clock rate. Can be programmed to achieve the desired clock cycle. Has encountered an emergency shut down the program's functionality. Each channel can be programmed to left-aligned outputs or center aligned lose. A motor drive module program: the relay on or off of the motor control to be adjusted by the switching speed of the car. Advantage of this program is relatively simple circuit, the drawback is that the relay response time is slow, easy damage, shorter life expectancy, reliability is not high. These management activities of laser pointer are carried out.
