“…We varied the external cavity length between 235mm and 250mm, corresponding to a maximum of 50ps time offset between the feedback signal and the main laser signal. This variation did not induce any noticeable changes in the temporal and spectral characteristics of the laser output, and the system showed stability similar to that reported for the near-IR systems [3][4][5] .…”

Self-seeded, gain-switched operation of an InGaN multi-quantum-well laser diode has been demonstrated for the first time. An external cavity comprising Littrow geometry was implemented for spectral control of pulsed operation. The feedback was optimized by adjusting the external cavity length and the driving frequency of the laser. The generated pulses had a peak power in excess of 400mW, a pulse duration of 60ps, a spectral linewidth of 0.14nm and maximum side band suppression ratio of 20dB. It was tunable within the range of 3.6nm centered at a wavelength of 403nm.

“…This approach has become known in the literature as the "injection seeding (locking) method," with the lasing parameters of the laser system. [9][10][11][12] This publication, using a number of inert gases as examples, systematically investigates the spectral properties of the narrow-band stimulated emission that appears when an active excimer medium is transirradiated with narrow-band controlling radiation that lies in the region of the longwavelength edge of its spectral contour. It is shown in Ref.…”

Amplifying the VUV radiation of atomic nitrogen in helium, argon, krypton, and xenon

et al. 2012

This paper discusses the spectral features of the amplification of narrow-band radiation of atomic nitrogen in the excimeric media of inert gases, including helium, argon, krypton, and xenon. Appreciable short-wavelength shifts (up to 0.026 nm) are detected in the spectra of the amplified radiation relative to the atomic emission lines of nitrogen that initiate this radiation. The observed shifts exceeded the instrumental resolution of the spectrometer that we used, were determined by the composition of the amplifying medium, and were independent of its excitation parameters under the experimental conditions. An explanation of the observed effect is proposed.
