Experimental and numerical study of Distributed-Bragg-Reflector tapered lasers

FIEBIG, C.; TRONCIU, V. Z.; LICHTNER, M.; PASCHKE, K.; WENZEL, H. (Springer Nature Switzerland, 2010)

We report results on experimental and numerical investigations of the output characteristics of edge-emitting distributed Bragg reflector tapered diode lasers emitting around 980 nm. The experimental results are well ...
Improving the stability of distributed-feedback tapered master-oscillator power-amplifiers

TRONCIU, V. Z.; LICHTNER, M.; RADZIUNAS, M.; BANDELOW, U.; WENZEL, H. (Springer Nature Switzerland, 2009)

We report theoretical results on the wavelength stabilization in distributed-feedback master-oscillator power-amplifiers which are compact semiconductor laser devices capable of emitting a high brilliance beam at an optical ...
Instabilities and Bifurcations of a DFB Laser Frequency-Stabilized by a High-Finesse Resonator

TRONCIU, V.; WENZEL, H.; WÜNSCHE, H. J. (IEEE, 2017)

Recently reported miniature configurations with semiconductor distributed feedback lasers under resonant feedback are considered theoretically. Limiting instabilities and bifurcations are systematically explored by combining ...
Investigations of external cavity diode lasers: Simulations, analysis and experiments

RADZIUNAS, M.; TRONCIU, V. Z.; LUVSANDAMDIN, E.; KÜRBIS, C.; WICHT, A.; WENZEL, H. (IEEE, 2014)

We report the results of numerical and experimental investigations of the dynamics in an external cavity diode laser device composed of a semiconductor laser and a distant Bragg grating, which provides an optical feedback. ...
Modal Behavior of an External Cavity Diode Laser

DUMANOV, E. V.; TRONCIU, V. Z.; WENZEL, H. (American Scientific Publishers, 2015)

This paper reports the results of numerical investigations of the modal behavior of an external cavity diode laser device composed of a semiconductor laser and a distant Bragg grating, which provides an optical feedback. ...
Numerical and experimental investigations of micro-integrated external cavity diode lasers

TRONCIU, V. Z.; RADZIUNAS, M.; KÜRBIS, Ch.; WENZEL, H.; WICHT, A. (Springer Nature Switzerland, 2015)

We report the results of numerical and experimental investigations of the electro-optical behaviour of an external cavity diode laser device composed of a semiconductor laser and a distant Bragg grating, which provides an ...
Numerical simulation of the amplification of picosecond laser pulses in tapered semiconductor amplifiers and comparison with experimental results

TRONCIU, V. Z.; SCHWERTFEGER, S.; RADZIUNAS, M.; KLEHR, A.; BANDELOW, U.; WENZEL, H. (Elsevier, 2012)

We apply a traveling wave model to the simulation of the amplification of laser pulses generated by Q-switched or mode-locked distributed-Bragg reflector lasers. The power amplifier monolithically integrates a ridge-waveguide ...
Theoretical studies of the generation of picoseconds pulses with two-section blue-violet semiconductor lasers

TRONCIU, V.; WENZEL, H.; KNIGGE, A. (IOP Publishing, 2012)

We report the results of theoretical investigations of the generation of sub-10 ps pulses by a blue-violet InGaN two-section laser. The principle of pulse generation is active Q-switching. We study numerically the influence ...
Travelling-wave analysis of extended cavity diode lasers

TRONCIU, V.; ARAR, B.; WENZEL, H. (Romanian Academy Publishing House, 2020)

We report results of numerical simulations of the dynamic properties of single-transverse mode diode lasers subject to an external optical feedback provided by a volume holographic Bragg grating. We use the traveling-wave ...
