Semiconductor Lasers are also called Laser Diodes. In practical application, the laser diode is affected by small current and temperature changes, which will lead to the fluctuation of output power of the laser diode. The output power of the laser diode is unstable. In order to ensure the stability, its necessary to design a control system to monitor the luminescence of laser diode. It controls the drive current of the laser diode to maintain the stability of the power output of the laser diode....(more)
Many electronic engineers always waste much time on finding the resistors, capacitor and inductors while welding the boards. Now good news comes. Analog Technologies, INC. spends almost one year to develop a kits to store the components, such as resistors, capacitors and inductors. Now, let me introduce this kind of kits briefly. Our Super SMT Resistor Kits have 128 individually lidded coverlets and one final top cover. The foam pad inside the top cover keeps all the coverlets closed even if the...(more)
Peltier cooler is also called the thermoelectric cooler, and its principle is the Peltier effect. Thermoelectric coolers can generate both heating and cooling thermal power when applying an electric DC current at different directions. The current direction determines cooling or heating. The current magnitude determines the effect of cooling or heating. A peltier controller is a must for controlling the peltier cooler automatically. The PID control system comes with high precision, which can be u...(more)
Since 1880 that the Curie brothers discovered the piezoelectric effect of tourmaline, it has been well studied and widely used in various fields for nearly 140 years. Piezoelectric ceramics is the most typical representative. The working principle of piezoelectric ceramics is actually the conversion of energy. Applying a pressure or pulling force to the piezoelectric ceramics to deform the surface of the piezoelectric ceramics will generate electricity at both ends of the ceramics. This is to co...(more)
Recently, we designed a high voltage 15A Laser driver with small size, ATLS15A218. It has both a wide input voltage range from 5.5V to 27V and a wide output voltage range from 0.1VVPS to 0.8VVPS. At the same time, it allows driving one or more laser diodes and its current can be as high as 15A. There is no need for heat sink with high efficiency. The output noise is low. It has a very small package with a 6 sided metal enclosure to prevent the controller and other electronics from interfering wi...(more)
With the rapid development of science and technology, semiconductor laser technology has penetrated into various fields of national economy and national defense construction. It has a wide range of applications in the long-range communications, laser radar, digital signal storage and recovery, laser ranging, robotics, holographic applications, medical diagnosis and so on. However, semiconductor lasers are harsh on working conditions and can result in a drastic deterioration or failure of perform...(more)
SMT/SMD resistor kits is a chipset package designed for circuit design, experiment and debugging by Analog Technologies, which greatly facilitates the management of SMT components and has obtained the national patent. The Component Kits include SMT/SMD resistor kits, SMT/SMD capacitor kits and SMT/SMD inductor kits, totally three series. Now I will introduce a new super surface mount resistor kit R04B760V50-20D. The external dimension of the SMT resistor kit are 309mm242mm40mm (L * W * H), which...(more)
When designing a laser system, the first thing needed is to make decision: design a laser driver or use an off-the-shelf laser driver. Which way is better? Design a Laser Driver vs. Using an Off-the-shelf Laser Driver It is apparent that designing a laser driver will save money in the long run for high volume production laser systems. But the cost for this route is not low: high design cost, long design time, high risk to fail or result in sacrificed performance because designing a good laser dr...(more)
