Laser driver is an electronic module, which is designed for driving a serial of diode lasers. High voltage laser driver features an input voltage between 4.75V to 16V. this laser driver is of high efficiency, so it generates small amount of heat, thus, there is no need for a heat sink for normal operation. This laser driver has a wide input and output voltage range and high output current capability. Moreover, it outputs low noise with high efficiency. ...(more)
An oscilloscope can measure noise, but for ultra low noise, such as nV and V level noises, its hard to measure. There is a noise measurement amplifier ATNMA1.0 , which is used to test and measure ultra low noise that cant be measured by an oscilloscope. This noise measurement amplifier can detect and amplify the noise signals by touching the selected point. There are seven magnifications, 10,000, 30,000, 100,000, 300,000, 1,000,000, 3,000,000, 10,000,000. ...(more)

By Gang Liu, Nan Shi, and Hongtao Zhou, Analog Technologies, Inc. Chopping a laser beam is often a necessary practice. For a diode laser, it is much simpler and less costly to chop the beam electrically, rather than mechanically. The output laser beam power, PO, versus the laser diode input current, ILD, characteristics are shown in Fig. 1. Fig. 1 Output Laser Beam Power vs. Laser Input Current In this figure, PO is the optical output power of the laser diode; ILD is the laser diode input curren...(more)
