Fiber Laser Schematic Diagram. Schematic diagram of a single mode fiber smf without and with a thermally expanded core spliced to a larger core large mode area lma fiber a and a tapered lma fiber b. This means that we can use a cheap diode laser pump source at 980nm and we get a very high quality and potentially very high power beam out at 1550nm.
Typical presstek fiber coupled laser diode ptfcld1 jpg. Within the doped fibre we have our laser medium which is the erbium atoms. The laser is a single stage fabry perot system consists of pump laser diode modules pump combiners er bragg gratings fbgs an ytterbium doped er and an endcapped delivery er.
To create our laser cavity we add bragg gratings.
Opto power high power fiber coupled laser diode overall view fcld3 jpg. Figure 1 shows the schematic diagram of our 5 kw single mode er laser. The power of fiber lasers are constantly being improved and developed and we now stock fiber lasers that have a power output over 6kw. Typical 1 watt fiber coupled diode laser showing interior construction fcld1 jpg.
