High-Brightness Quantum Well Tapered Lasers

Efficient generation of 509 nm light by sum-frequency mixing between two tapered diode lasers

“…high power, good beam quality and narrow spectral linewidth [8][9][10][11]. Frequency doubling of such lasers has been demonstrated at different wavelength regions [12][13][14][15].…”

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

“…High-power, diffraction-limited diode lasers can be realized by the technology of lasers with a tapered gain-region (Kintzer et al, 1993;Donnelly et al, 1998;Wenzel et al, 2003;Paschke et al, 2005;Sumpf et al, 2009;Fiebig et al, 2010). The tapered laser devices can be used in applications where narrowspectrum is not needed such as photodynamic therapy, but for other applications such as a pump source for UV light generation, the spectral quality of these devices has to be improved.…”

High-power passively mode-locked tapered InAs/GaAs quantum-dot lasers

“…Semiconductor lasers with high output power and good beam quality are desirable for many commercial and scientific applications, such as medical treatments, biomedical imaging, free-space optical communications, optical pumping of solid-state lasers, laser display technology, material processing, and nonlinear optics [1][2][3][4][5][6][7]. Edge-emitting mode-locked semiconductor lasers with flared (tapered) waveguides are well-known for their capability to deliver high output power as well as ultrashort pulses.…”

“…Edge-emitting mode-locked semiconductor lasers with flared (tapered) waveguides are well-known for their capability to deliver high output power as well as ultrashort pulses. Tapered lasers typically consist of a straight ridge-waveguide section coupled to a tapered section [2][3][4][5]. While the straight waveguide acts as a spatial filter in the cavity, the tapered section of increasing width delivers high power.…”
