Master Oscillator Power Amplifier Pulsed Laser

MOPA (Master Oscillator Power Amplifier)

This fiber laser will consist of three stages:

1st: Master Oscillator (this is the stage that will contain the graphene and will produce the pulsing)

2nd: Single-Mode Power Amplifier

3rd: Double-Clad Power Amplifier

Master Oscillator with graphene as saturable absorber:

The lengths of Erbium-doped fiber are chosen based on RP Fiber Power simulation:

Application of Graphene to the Tip of a Fiber Connector

We want to use graphene as a saturable absorber for our MOPA

In order to do that, we need to get graphene onto the tip of a fiber connector:

Cut Out a Small Square From the Graphene Sample

To cut the graphene sample, use an exacto blade and press firmly onto the foil, no sawing motion

Once the small square is free, place it onto a glass slide and with another glass slide cover it

Press the two slides together to flatten the foil so that hopefully the suction in the next step will be strong enough to hold it in place
