We report on a high frequency modulation of an external cavity diode laser near 780 nm. Employing a LiTaO3 crystal as an electro-optical modulator, frequency modulation of the laser emission up to 20 kHz with modulation depths of 1.5 GHz has been ach

We report on the generation of continuously tunable high power radiation near 780 nm by using a travelling wave GaAs/GaAlAs amplifier with a laterally tapered gain region seeded by a low power external cavity diode laser. Stable single frequency oper

We report on a broadly tunable external cavity semiconductor laser near 825 nm employing a grating mounted in grazing incidence. The laser system is tunable without mode hops in the wavelength range from 800 nm to 840 nm with output powers up to 6.5

Broadly tunable external-cavity diode lasers with emission wavelengths in the visible and near-infrared spectral region are compact and reliable light sources, which are increasingly used in a variety of applications, including high resolution spectr

Summary form only given. In trace gas detection on absorption spectroscopy there is a need for widely tunable narrow bandwidth mid infrared light sources. To our knowledge, we report on the first continuously tunable difference frequency generation s

Summary form only given. In trace gas detection by using absorption spectroscopy widely tunable narrow linewidth mid-infrared light sources are needed. We report what we believe to be the first realization of a continuously tunable DFG spectrometer w

A new external-cavity diode laser system based on an extended version of the Littman configuration is investigated. In our laser system the tuning mirror is replaced with a second grating mounted at the Littrow angle. This double-grating design provi

External cavity diode lasers are attractive light sources for many applications in metrology, high resolution spectroscopy and gas monitoring because they have small linewidths and broad tuning ranges in combination with a compact size, a simple hand
