Mephisto MOPA Lasers

Mephisto MOPA Lasers

…Mephisto to seed one or more cascaded amplification stages, resulting in a Master Oscillator Power Amplifier (MOPA) configuration. Mephisto MOPA laser incorporates a Mephisto S oscillator followed by 1 to 4 stages of power amplification, pumped by fiber-coupled laser diode pump modules. The seed and…

…and etalons; in other cases, the laser can be "seeded" with a low-power CW or Q-switched narrow-linewidth laser that is
easier to control than the higher-power stage. This approach, called "injection seeding," uses a MOPA (master oscillator, power amplifier), conceptually
splitting the…

MOPA design
To overcome this power limitation, Coherent uses a Master Oscillator Power Amplifier (MOPA)
approach. The NPRO oscillator is used as a seed source in this configuration. The output of this
seed laser is amplified gradually by using up to four amplification stages…

…to develop high-power, modelocked oscillators with 50 to 150 pulse widths, and higher-energy, amplified systems with 200- to 350-fs pulse durations. MOPAs: High power, fast repetition The time-proven route to high power with low noise is to use a master oscillator/power amplifier (MOPA)…
