Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers [PDF]
, 2005 We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode ...

Volume Bragg grating external cavities for the passive phase locking of high-brightness diode laser arrays : theoretical and experimental study [PDF]
, 2011 We describe the theoretical modeling of the external-cavity operation of a phase-locked array of diode lasers in two configurations, the self-imaging cavity based on the Talbot effect and the angular-filtering cavity. Complex filtering functions, such as

The Effect of the Pillar Ripple on the Reverse Recovery in Superjunction MOSFETs
Power Electronic Devices and Components, 2022 Fast dI/dt and oscillations often are the causes of failure during the reverse-recovery of superjunction MOSFETs. These issues become more prominent with shrinking the pitch size of the superjunction in an attempt to improve the overall performance from ...

Nasal septal Swell Body reduction a diode laser [PDF]
Russian Otorhinolaryngology, 2019 The nasal swell body (NSB) is a structure in the form of mucosa thickening from the nasal cavity bottom up to the middle nasal concha. The septal swell body was first described by Wustrow in the 17th century, he indicated it as an “intumescentia septi nasi anterior”; later, in 1900, P.
