High Power Pulsed Fiber Laser

The 1550nm short pulse fiber laser for lidar is an eye safe pulsed laser sources for lidar with high peak power and high pulse energy.

High power pulsed fiber laser.

Enabling technology for high power fiber lasers fiber lasers have many advantages over bulk glass lasers. Calculate laser specs and requirements based on fiber size or calculate the necessary fiber size for a given laser light source. A full front panel with lcd menu driven display and a remote interface make this unit is highly flexible for many research and testing applications. The range of average powers is from 100 w to 5 kw the pulse energy is up to 100 mj and the beam spot size is optimized for high throughput.

Higher power pulsed fiber lasers with higher m 2 value are optimized for large surface area treatment applications. These 1550nm fiber lasers deliver up to 10 watts of cw 10kw peak pulse output power. Thus it can perform high resolution images. Spectral output modification through fiber doping the last stage amplifier for the millijoule level all fiber laser system from advalue photonics uses a silicate glass double clad polarization.

Fiber optic cables for transmission of high power laser pulses. This paper reviews cw and pulsed fiber lasers with a focus on ydfl for its high conversion efficiency. They are an affordable fully integrated bench top laboratory r d instrument. In the following discussions of high power fiber lasers output power and beam quality 7 constitute two important parameters.

All the setup is based on. Joe thomes jr a melanie n. The shorter the gain fiber the better the mitigation of nonlinear optical effects when building a high power or high energy pulsed fiber laser. The mako pulse width 2 to 6 0ns and repetition rate 10 to 4 000 khz are continuously adjustable through an analog input control.

We have recently developed a high power single frequency all fiber mopfa using high reliability passive components. The mako fiber laser series is a compact dual mode pulsed and cw oem fiber laser capable of delivering either high peak power 5 kw pulses or cw power greater than 1w with near gaussian profile m2 1 1 output beam. High power pulsed lasers are commonly deployed in harsh environments like space. Compact pulsed laser transmitter finds its utility in applications like 3d scanning mapping telemetry and also in supercontinuum generation thanks to the high peak power operation.

Blairb anasa goddard space flight center greenbelt md usa 20771. The calculator includes the capability to make calculations for pulsed laser systems and continuous wave laser systems. This mopfa was used in the first experimental demonstration of a fiber laser based wind lidar with more than 10 km range. Bmei technologies 7404 executive place suite 500 seabrook md usa 20706.

The all fiber design guarantees the robustness and the maintenance free operation of the fiber laser module. The experimental setup for the pulsed fiber laser is shown in fig.
