The advantage of quantum cascade lasers over other lasers lies in the cascade process. Electrons jump from high energy level to low energy level without any loss, and then inject into the next process to illuminate again. This cascade process "circulates" these electrons, creating an amazing laser. The invention of quantum cascade lasers is a milestone in the field of semiconductor lasers.(more)
Metal Ceramics Heater is short for MCH and can also be named as MCH ceramic heating element, alumina metallic ceramic heating element, HTCC ceramic heating element, and ceramic heater. As for its materials, MCH is made up of high melting point metal heating resistance slurry such as tungsten or molybdenum-manganese printed onto 96% alumina casting ceramic green body according to the design requirements of the heating circuit. Now, please find the physical photo of Metal Ceramics Heater produced by Analog Technologies, Inc.(more)

Do you know how to identify a good laser driver? Of course, different people hold different point of views. Generally speaking, good laser drivers should be high speed, low noise, high efficiency, constant current and high voltage. Then, what you need to be is to select the parameters that suit your requirements most closely. Analog Technologies, Inc has developed various kinds of high quality laser drivers, tec controllers and smt kits; Now, I will introduce one constant current laser driver, whose part No. is ATLS6A202D. Please take a look at its physical photo of this laser driver.(more)

Are you looking for a low noise and constant current laser driver with a compact size? ATLS500MA106 is a best choice for you. This laser driver features ultra low noise and constant 500mA current, which is packaged in a metal enclosure with six sides, blocking electro-magnetic interference from other surrounding electronics.(more)
Diode laser drivers can be categorized by output stage type: PWM type and linear type. The PWM type laser uses a high efficiency PWM output stage as the power output, which features high efficiency but high ripple noise and low speed. When the current is more than 1A, we recommend a PWM mode laser driver. CWD-01-V2-D is one of the PWM type laser drivers.(more)
Do you know what does a laser driver mean, and how to choose a good and high quality laser driver in such a complicated and huge internet? As an engineer engaged in the analog electronics for more than 10 years, let me give you some guidance. First, laser driver is an electronic module designed for driving diode lasers. Then what features or characteristics should a good laser driver have are also very essential, such as constant current, high efficiency, low noise, high reliability, zero EMI, and small package and so on. Today let me introduce one high efficiency constant current laser controller, whose part No. is ATLS2A201. Please take a look at its physical photo of this laser driver.(more)
In recent years, with the rapid development of optoelectronic technology, diode lasers have been widely used in medical, defense, measurement and other fields. The change in ambient temperature directly affects the wavelength of the diode laser. Since the temperature has a great influence on the quality of the diode laser, in the case of a constant current, the laser wavelength will increase by about 0.1nm for every 1°C increase in temperature, and too high a temperature will cause the diode laser to age or even be damaged. The diode laser is a device that is electrically sensitive and expensive, so our controllers must provide monitoring, limiting and overload protection capabilities.(more)
