Due to the design of the so-called "high power" In fact, only small and medium-sized power, so not quite care about the efficiency of the power supply. In order to achieve the requirements of accuracy, stability, so we designed the program to select the linear power supply. The adjustment device operates in a linear series of negative feedback inhibition of the ripple. In order to achieve the precision and stability requirements, two adjustment module, the former a regulator chip, the expansion flow, transported to an adjustment module, and then adjust to achieve the suppression of ripple and noise reduction requirements. The following is a basic block diagram of the basic block diagram of the design in Figure 3-1: Figure 3-1 voltage source. Electricity through the grid filter (to prevent a variety of high-pressure situation arising as a result of unusual circumstances, such as lightning) into the transformer. So that the customer can use green laser pointer with more ease and convenience.
Dropped 2lV (peak) by the regulator blocks the expansion flow circuit composed of an adjustment of the circuit after the rectifier filter; stage series - sampling - feedback - to adjust the final output. Power supply voltage source, this part of the circuit is a series of negative feedback adjustment circuit to achieve constant current. The only sampling the current sampling. The reason is to ensure accuracy. Taking into account the laser protection, the need to use the slow start circuit, the current output before you start, semiconductors, a smooth transition to the normal work area when not to. In addition, to avoid interference reasons, the circuit for the time being should not be designed for CNC or machine control, this will bring a lot of noise. So that the customer will not feel cold when they hold green laser pointer by hand.

Throughout the system, the design of appropriate feedback section to have a very stable and fast tracking the effect of the output signal and the reference signal, is the main part of the design and key links. Basic Analysis: From the above analysis we can see: our system is actually two to achieve with a design method. The two systems can in fact be simplified as shown in Figure 4-1, a correction method, get the output signal to track the reference signal by a certain percentage, and stable and sensitive changes in the tracking process. It will make the customer hold green laser pointer more conveniently and comfortable.
So, our work is actually constructing an appropriate error caused by the transmission coefficient H (s) of the input signal and output signals meet the following requirements: First, we should create a stable system, to prevent the transfer function of any system of non-stable to improve the performance of the system-defined error signal, followed by talk about: Obviously, in order to eliminate the ripple and noise requirements, the requirements increase with time is reduced to 0, namely: the definition of the effectiveness of the system; the definition of tracking speed: set error signal is reduced to the initial error when used for the error decay time parameters are: the definition of the sensitivity of the system, then as our feedback system. green laser  has the anti-impact characteristic.

The protection of the laser diode driver circuit is used HY5650 for over-temperature protection circuit to achieve the protection of the semiconductor laser drive power. It is the importance of customer’s feedback of  green laser pointer  .
Following a brief introduction to first HY5650 chip. HY5650 is an ultra-small thermoelectric ratio of temperature control cooler (referred to as the TEC). This device is suitable for the application of the front control panel and the digital readout is not necessary for fixed temperature of the heating or cooling. The HY5650 using a thermistor bridge to accurately measure and specification TEC comes with the device temperature. With appropriate cooling equipment, power supply will provide up to 2 amps of current to the TEC and will provide a voltage of 5-12 volts. The HY5650 the basic parameters such as Table 3-2: HY5650 the basic parameters. The HY5650 the inner workings of Figure 3-6: Figure 3-6-HY5650 the inner workings of the diagram. It is the laser effect of  green laser pointer  they want.
The semiconductor laser power fault protection mechanism so that the expensive LD array from damage. Circuit protection is a core part of the entire power supply consists of over-temperature protection, overcurrent protection, undervoltage protection, and overvoltage protection. In addition to the over-temperature protection circuit, the other protective circuit is relatively simple, the CPU via a constant current of the detection system, the voltage signal to control the power supply to run, play the corresponding protective function. LD with a number of parameters have a close relationship with its junction temperature. When the junction temperature rise of LD band gap narrowing, leading to the laser wavelength moves to longer wavelengths [11,12], the LD threshold current also increased with temperature increase. If there is no effective temperature control system. It is as per where  green laser pointer   will be used.
Constant current injection, when the LD temperature change, the output optical power will be more ups and downs. Operating temperature will affect the life of the LD, LD case temperature is increased to 30 ° C, its life is about to reduce an order of magnitude, usually the temperature of LD should be controlled within 0.05 ° C [13] in order to ensure that the current modulated LD influence of temperature will not result in serious consequences. In the past, for small and medium-sized power LD often simple passive cooling or water-cooled. These two methods the results are not very good and are unable to achieve the purpose of further temperature control, can not set the system to work in a specific temperature range, while the semiconductor thermoelectric cooler (TEC) temperature control devices have good control effect. What is the purpose of the laser effect of   green laser.
