Feedback-induced destabilization of a laser diode using wavelets
نویسندگان
چکیده
We analyze the feedback-induced destabilization process of a single-mode laser diode with the wavelet transform ~WT!. We consider transients following an abrupt switch on of the feedback, for feedback levels strong enough so that the final state of operation of the laser is the coherence-collapsed state. The transient regime involves multiscale interactions that exhibit strong localization in both frequency and time, and we demonstrate that by using the WT we can characterize the transient dynamics and capture the essential features associated with the destabilization process in a relatively simple form. @S1050-2947~97!00905-0#

Comparison of Soft Tissue Thermal Changes Induced by Three Types of Diode Lasers at 810, 940, and 980nm Wavelengths
Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...
متن کاملFrequency locking of tunable diode lasers to a stabilized ring-cavity resonator
We demonstrate a technique for locking the frequency of a tunable diode laser to a ring-cavity resonator. The resonator is stabilized to a diode laser which is in turn locked to an atomic transition, thus giving it absolute frequency calibration. The ring-cavity design has the principal advantage that there is no feedback destabilization of the laser. The cavity has a free-spectral range of 1.3...

We demonstrate a technique for locking the frequency of a tunable diode laser to a ring-cavity resonator. The resonator is stabilized to a diode laser that is in turn locked to an atomic transition in rubidium, thus giving it absolute frequency calibration. The principal advantage of the ring-cavity design is that there is no feedback destabilization of the laser. The cavity has a free-spectral...
متن کاملUsing of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser
Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...
