Improved fiber probe optics for a monochromator

Fiber Optics

Dramatic improvements in the development of low-loss materials for optical fibers are responsible for the commercial viability of fiber-optic communications. Corning Incorporated pioneered the development and manufacture of ultra-low-loss glass fibers. C 0 R N I N G 272 Fundamentals of Photonics

Fiber-lasers for ultrafast optics

The current status of a fiber-based ultrafast technology is reviewed. Pulse generation techniques capable of producing femtosecond pulses are discussed. Here we describe passive and active–passive mode locking techniques as well as linear and nonlinear fiber amplifiers. Thirtyfemtosecond pulses may be generated directly from fiber oscillators or by implementing pulse compression techniques. The...

Fiber Fourier optics.

The Fourier transform of a coherent optical image can be evaluated physically by use of a single lens plus free-space propagation, thereby providing the basis for the field of Fourier optics. I point out that one can similarly evaluate the discrete Fourier transform of a sampled or pixelated optical array physically by passing the discrete array amplitudes through a network of single-mode fiber...

A modified Seya–Namioka monochromator with improved light intensity transfer

A monochromator with improved focusing properties has been designed and constructed using a novel optical geometry based on the Seya–Namioka concept. The only optical elements used are a spherical grating and a cylindrical mirror mounted in the exit arm within the Rowland circle , retaining the Seya–Namioka scanning simplicity while minimizing reflections. This optical system compensates for th...
