We have employed a quadrature detection technique to measure theDoppler signal from a moving target. We mix a circularly polarizedreference with a linearly polarized signal to produce an output thatcontains the real and the imaginary parts of the int

Quadrature detection techniques have been applied to images obtained from a Mach-Zehnder interferometer with differently polarized beams to yield the real and the imaginary parts of the diffracted fields simultaneously. This approach eliminates the n

Erbium doped YAG is an intriguing laser material which lases directly at 1645nm when pumped at either 1473nm or 1532nm, all of which are in the eye-safe band. However, a laser made from this material is not particularly straightforward to design. Er:

Erbium doped YAG, lasing at 1645 nm from a 1532 nm pump, is an intriguing alternative to wavelength shifted 1-micron lasers for eye-safe applications. In this paper, we will report on an end-pumped Er:YAG laser that employs diamond disks for heat ext
