TL;DR: In this paper, a widely tunable optically pumped distributed Bragg reflector (DBR)-free semiconductor disk laser with 6'W continuous wave output power near 1055'nm when using a 2% output coupler was reported.
Abstract: We report a widely tunable optically pumped distributed Bragg reflector (DBR)-free semiconductor disk laser with 6 W continuous wave output power near 1055 nm when using a 2% output coupler. Using only high reflecting mirrors, the lasing wavelength is centered at 1034 nm and can be tuned up to a record 80 nm by using a birefringent filter. We attribute such wide tunability to the unique broad effective gain bandwidth of DBR-free semiconductor disk lasers achieved by eliminating the active mirror geometry.

TL;DR: In this paper, the magnetic field tuning in conjunction with the conventional current tuning is shown to significantly increase the versatility of diode lasers in high-resolution spectroscopy, and details of the tuning characteristics for fields up to 90 kG are presented.
Abstract: Tunable laser spectroscopy measurements on low‐pressure gases have been performed using magnetic‐field‐tuned lead‐salt semiconductor diode lasers in the 4‐ to 7‐μm region. Use of magnetic field tuning in conjunction with the conventional current tuning is shown to significantly increase the versatility of diode lasers in high‐resolution spectroscopy. Details of the tuning characteristics for fields up to 90 kG are presented.

TL;DR: In this article, the transverse distribution of intensity noise in the far field of semiconductor lasers has been experimentally studied and it has been found that a large amount of noise is present in higher-order non-lasing transverse modes parallel to the diode junction.
Abstract: The transverse distribution of intensity noise in the far field of semiconductor lasers has been experimentally studied. For a single-mode edge-emitting laser, it has been found that a large amount of noise is present in higher-order nonlasing transverse modes parallel to the diode junction. In the case of a spatially multimode vertical-cavity surface-emitting laser, each mode exhibits a large noise, but these noises show strong anticorrelations.
