How can be use the CW diode laser with sample from fiber optics part to obtained laser fiber?
Please explain: do you mean: how to harness the pump diode power of a pump module to generate laser emission from a rare-earth ion-doped fiber?
Use a directiobal coupler at the input of your fiber laser. Couple the pumping source i.e. the diode laser at one port and at the other port you can use a bragg grating to form the laser resonator cavity. For example in case of Er-doped fiber laser we use 980 nm as pumping source and the laser is at 1550nm. In that case we use a directional coupler whos two ports are 980 and 1550 nm. Now through 980 port we couple the diode laser and at 1550 port we use a bragg grating. At the output of the fiber laser fiber air interface's 4% reflectivity is enough to form the resonator cavity. To my knowledge this is the simplest set up for fiber laser.
Dear Nabarun Saha,
yes this your answer, was very satisfy which I was looking for, can you sent my an articles or set up for this your idea.
thank
regard
