Variable xy-UV beam expander for high-power laser
... must be made of UV grade fused silica for high transmission at 355 nm. Fortunately, the CVI Melles Griot catalog offers a large selection of standard plano-convex and plano-concave cylinders in UV grade fused silica. A minimum of three elements is needed to produce a variable beam expander which pro ...

In text you refer to OAP mirrors as 2nd etc, In fig, they are labeled
... I collected a set of images of the beam immediately after concave lens at the beginning of the optical layout to ensure the linearity of the CCD. I collected images of the beam at different widths as it grew larger through the beam expander by shifting the camera. I then loaded these images into Mat ...

Imaging and focusing of an atomic beam with a large period
... an object (see Fig. 1). The aperture defining the diameter of the lens was 25 btm wide and placed 15 mm upstream from the standing wave. The lateral (z) position of the 25 lim slit could be adjusted by a piezo translation stage with high precision allowing us to set the position of the atomic beam w ...

Hence, in addition to the optical path length change induced by the motion of the reflecting surface, a change also results from the variation of refractive index with ...

Laser beam profiler
A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers — ultraviolet, visible, infrared, continuous wave, pulsed, high-power, low-power — there is an assortment of instrumentation for measuring laser beam profiles. No single laser beam profiler can handle every power level, pulse duration, repetition rate, wavelength, and beam size.
