Abstract :
In this paper, frequency-doubled diode laser based on a transmission diffraction grating for high-resolution atomic absorption spectroscopy in the UV at 325 nm is developed. The fundamental single-mode beam is frequency-doubled with a lithium iodate crystal. And CW output power of 40 nW was obtained.
