Wave Forms: A New Laser Tool

Mark Brodsky

An innovative laser design provides pulsed energy differently than traditional mirror/Q-switch cavities. It offers optical engineers a new option for quick processing and fine pulse control.

In a new laser design that uses an arrangement of single-pass amplifiers, the single-pass master oscillator-pulse amplifier (MOPA) has no mirrors or Q-switch because the power is released in one single cascading pulse down a charged fiber gain media. This allows the laser pulses to form arrangements called wave forms—specially designed seed pulses combined with precise energy setting in the laser amplifiers.
