Tunable high-power narrow-spectrum external-cavity diode laser at 675 nm as a pump source for UV generation

The still unknown azobenzene - Wavelength dependent photoanisotropy in amorphous azobenzene polymers

“…A continuous wave 670 nm laser was used for irradiation at longer wavelengths. The 670 nm laser was an external cavity tapered diode laser operated in the Littrow configuration with an external diffraction grating for tuning [15]. The laser was operated at relatively low power and the output was spatially filtered through a pinhole to obtain a pure TEM 00 output beam.…”

Stabilization of wavelength of diode laser radiation. Dynamic characteristics of Peltier Elements

“…Reliability and simplicity of arrangement of the systems based on fiber components stipulate their use in stringent operating conditions [3], as well as in space engineering. Thus, use of radiation of laser diode in the capacity of driving diode for infrared Fourier spectrometer requires higher level of wavelength stability to the extent of its connection мощности [1], и прецизионные диоды с шириной линии от 30 кГц до 2 МГц и мощностью до 1 Вт [2]. В статье рассмотрены условия стабилизации пара-метров второй группы.…”

“…For the last half a century, semiconductor lasers have covered long way, and their technology have had many modifications and improvements. Lasers can be divided into highpower diodes, which allow obtaining up to several tens of Watts of optical power [1], and precision diodes with the line width of 30 kHz to 2 MHz and power up to 1 W [2]. The conditions for stabilization of parameters of the second group are considered in this article.…”

Red Tunable High-Power Narrow-Spectrum External-Cavity Diode Laser Based on Tapered Amplifier

“…The emission wavelength of the laser system is tuned widely by rotating the diffraction grating because of the broad gain bandwidth (a few tens nanometers) of the tapered device. The emission spectrum of the laser system is narrowed significantly compared with the freely running tapered lasers (from a few hundreds picometers to a few tens picometers) due to the dispersion of the diffraction grating and the narrow aperture of the tapered device in the fast axis direction Chi et al, 2010Chi et al, , 2011. The laser is TE-polarized, i.e., linearly polarized along the slow axis.…”
