These include frequency-stabilized diode lasers used in spectroscopy, nonlinear frequency conversion as well as high-precision laser measurement technology. These lasers have unique attributes that often compel their use in system designs: small size, excellent power efficiency, and the ability to b modulated at high rates. This monochromatic property is rooted in the fundamental working principle of the laser that al ays contains a frequency-selective element. Examples for these elements in the case of diode lasers include external resonators eady lead to very narrow. It consists of a dedicated current source and an impedance matching circuit both. First laser diodes were made from GaAs p-n homojunctions, required very high current and could be operated only in the pulsed mode with cryogenic cooling and heatsinking.
