Abstract: A fiber-MOPA includes a seed-pulse source followed by fiber amplifier stages. The seed pulse source delivers signal pulses for performing a laser operation and delivers radiation between the seed pulses to maintain the collective average of the seed pulse power and intermediate radiation power constant. Keeping this average power constant keeps the instantaneous available gain of the fiber amplifier stages constant. This provides that the seed pulse delivery can be changed from one regime to a next without a period of instability between the regimes.

Abstract: A socket terminal assembly is configured to electrically connect a contacting area of an integrated circuit with a corresponding connection region of a substrate, the socket terminal assembly comprising a socket shell including a first end configured to contact the corresponding connection region of the substrate and a second end defining a first open cavity; a pin including an end defining a second open cavity; and a coiled spring interposed between the socket shell and the pin, the spring including a first end section received within the first open cavity and a second end section received within the second open cavity.
