Construction and design of a high-power double-pass laser diode amplifier
نویسنده
چکیده
Diode lasers have many benefits, but it is very hard to make diode lasers that have both high spectral purity and high intensity. In this masters thesis a diode laser amplifier with a gain of G=4 is constructed. The amplifier is a double-pass semiconductor laser amplifier and the active region is 100 ~m broad. The amplifier is operated at 793 nm using an external cavity diode laser as master laser. This thesis also includes an overview of some aspects of the theory of laser diodes relevant to the field of amplification in semiconductors. Different aspects associated with the design of the amplifier constructed in this work are also considered both from a scientific and from a cost-efficiency point of view. The possibility of achieving even further amplification towards G=lO and beyond is also discussed.

Treatment of lentigines by a novel high power diode laser at 755 nm: a case report
The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...
متن کاملBroad-area diode laser system for a rubidium Bose-Einstein condensation experiment
We report on master-oscillator power amplification using a broad-area laser diode (BAL) emitting at a wavelength of λ = 780 nm. The master oscillator is an injection-locked single-mode diode laser delivering a seeding beam of 35 mW, which is amplified in double pass through the BAL up to 410 mW. After beam shaping and spatial filtering by a single-mode fibre we obtain a clean Gaussian beam with...
