Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers.
We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode-hop-free tuning without the need for a mechanically optimized pivot-point mount. Furthermore, synchronized diode injection-current tuning allows...
متن کاملRobust external cavity diode lasers with implemented antirefl ection coated “blue” laser diodes and their performance in atom absorption spectroscopy
Compared to traditional lasers, diode lasers are generally small, reliable and easy to operate. However, tuning characteristics of many commercially available standard diode lasers are often far from ideal. External Cavity Diode Lasers (ECDL), in which antirefl ection (AR) coated Fabry Perot laser diodes can be utilized, provide an attractive alternative with wavelength tuning ranges of up to 1...
متن کاملWidely tunable diode lasers advance microresonator research
Due to a very distinct spectrum of resonant frequencies, the characterization of optical microcavities calls for widely tunable sources of continuous wave laser light, offering suitably narrow linewidths and single-mode operation over the entire tuning range. This is why external cavity diode lasers, which allow for mode-hop free wavelength tuning, often over more than a hundred nanometers, hav...
متن کاملWidely tunable rapid-scanning mid-infrared laser spectrometer for industrial gas process stream analysis.
A mid-infrared spectrometer with a tuning range of >400 cm(-1) in the C-H stretching region of the spectrum has been designed and constructed. The spectrometer is based on the difference-frequency generation of two tunable diode lasers in periodically poled lithium niobate waveguides. Tuning is achieved by varying a single parameter, the wavelength of one of the near-infrared input lasers. The ...
متن کاملSingle-frequency tunable 447.3 nm laser by frequency doubling of tapered amplified diode laser at cesium D1 line.
A continuous single-frequency tunable blue laser at 447.3 nm is developed by external-cavity frequency doubling of a tapered amplifier-boosted continuous-wave diode laser at cesium (Cs) D1 line. A maximum blue power of 178 mW with 50.8% conversion efficiency is obtained. It can be continuously tuned over a range around 1.6 GHz as the diode laser frequency is scanned across the F=4→F'...
