CdSiP2 (CSP) is a nonlinear optical chalcopyrite semiconductor developed as a wider-band-gap analog of ZnGeP2 (ZGP) to enable mid-infrared generation. Two laser architectures were explored to pump CSP crystals at 2 microns. The first was a ring OPO w

A 1940 nm thulium fiber oscillator producing >550 peak watts at 10% duty cycle is presented. The laser, pumped by seven high-brightness fiber-coupled 793 nm diodes, is single transverse mode at 45% optical conversion efficiency.

Design trades for optimized second harmonic conversion efficiency of high-peak power Er:fiber source
Publikováno v:
Laser Technology for Defense and Security XIV.
Second harmonic generation efficiency of a pulsed Er fiber laser with periodically poled lithium niobate (PPLN) is optimized by varying input pulsewidth. The Er-doped fiber amplifier was a 3-stage, 1550 nm amplifier with 1-10 ns variable pulsewidth,

We have developed a packaged fiber amplifier configuration that allows for nearly two orders of magnitude of pulse width adjustment from 1ns to >800ns. This has been developed for both the 1-micron and 1.55-micron spectral regions. Our 1.55-micron fi

We have recently demonstrated an Er:Yb fiber amplifier pumped off-peak at 940 nm which achieved 50.5% slope efficiency compared to 40.2% slope efficiency when pumped on-peak at 976 nm, the typical pumping wavelength for Er:Yb fiber. To further unders

High power continuous and pulsed fiber lasers and amplifiers have become more prevalent in laser systems over the last ten years. In fielding such systems, strong environmental and operational factors drive the packaging of the components. These incl

Compact, high power blue light in the 470-490nm region is difficult to generate due to the lack of laser sources which are easily convertible (through parametric processes) to those wavelengths. By using a pulsed Tm-doped fiber laser as a pump source

High power fiber lasers/amplifiers in the 1550nm spectral region have not scaled as rapidly as Yb-, Tm-, or Ho-doped fibers. This is primarily due to the low gain of the erbium ion. To overcome the low pump absorption, Yb is typically added as a sens

We compare large mode area (LMA) and single-mode (SM) double-clad fiber geometries for use in high power 1908nm fiber lasers. With a simple end-pumped architecture, we have generated 100W of 1908nm power with LMA fiber at 40% optical efficiency and 1
