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)

1. Does heat dissipation need to be provided during the use of the laser driver? A. The higher the operating temperature of the laser driver, the greater the loss of its operating efficiency, the greater the noise, and therefore the worse the current stability. Its operating case temperature is −40°C ~ 85°C, We recommend that its working temperature be around 50°C.(more)
