Fiber-optic amplifier

Directly modulatable laser

Arrangement for generating red, green and blue laser radiation

Fiber optical amplifier, has multimode dual core fiber with transversal mode selection element on it or in it near one end that suppresses higher modes than fundamental mode

Modulated optical fiber laser

Fibre laser for video projector etc, has polarizing fibre e.g. spliced onto end of lasing optical fibre

Optical fibre laser or fibre amplifier with refraction factor structure

Anordnung zur Erzeugung roter, grüner und blauer Laserstrahlung Arrangement for producing red, green and blue laser radiation

Faserverstärker Fiber amplifier

Short coherence light source for optical coherence tomography
