摘要： A frequency-tunable optical relay comprising one acousto-optic device (AOD) in a double pass configuration is provide. The AOD is configured to receive (a) an input optical beam propagating in a first direction toward the AOD from a first side of the AOD and (b) an electrical driving signal. The optical relay further comprises an output optical element array comprising a plurality of output optical elements disposed on the first side of the AOD. Each output optical element of the plurality of output optical elements is configured to provide a respective output optical beam substantially propagating either parallel or anti-parallel to a second direction. The plurality of output optical elements are spaced apart from one another in a third direction, which is transverse to both the first direction and the second direction.

摘要： A wavefront of a light beam that exits an acousto-optic material is estimated; a control signal for an acousto-optic system that includes the acousto-optic material is generated, the control signal being based on the estimated wavefront of the light beam; and the control signal is applied to the acousto-optic system to generate a frequency-chirped acoustic wave that propagates in the acousto-optic material, the frequency-chirped acoustic wave forming a transient diffractive element in the acousto-optic material, an interaction between the transient diffractive element and the light beam adjusting the wavefront of the light beam to compensate for a distortion of the wavefront of the light beam, the distortion of the wavefront being at least partially caused by a physical effect in the acousto-optic material.

摘要： The invention relates to an acousto-optic main beam splitter for a scanning microscope, which is embodied and intended to direct illuminating light having a preselected or preselectable illuminating light wavelength into an illumination beam path for illumination of a sample, and to direct detected light coming from a sample into a detection beam path. The acousto-optic main beam splitter is characterized in that a mechanical wave having an acoustic frequency associated with the illuminating light wavelength propagates, or multiple mechanical waves that have the same acoustic frequency associated with the illuminating light wavelength propagate, in the acousto-optic main beam splitter, both a portion of the detected light bundle having the illuminating light wavelength and a first linear polarization direction, and a portion of the detected light having the illuminating light wavelength and a second linear polarization direction perpendicular to the first linear polarization direction, being deflected out of the detected light bundle coming from a sample by interaction with the one mechanical wave or by interaction with the mechanical waves, and are thereby removed from the detected light bundle; and/or the acousto-optic main beam splitter being embodied to direct, by interaction with the one mechanical wave or by interaction with the mechanical waves, both the portion of illuminating light that has the preselected illuminating light wavelength and a first linear polarization direction, and the portion of illuminating light that has the preselected illuminating light wavelength and a second linear polarization direction that is different from, in particular perpendicular to, the first linear polarization direction, into an illumination beam path for illumination of a sample.

摘要： Aspects of the present disclosure include methods for producing an output laser beam having two or more angularly deflected laser beams (e.g., for irradiating a sample in a flow stream) with a predetermined intensity profile. Systems for practicing the subject methods having a laser, an acousto-optic device, a radiofrequency generator and a controller for adjusting the amplitude of the radiofrequency drive signals to produce an output laser beam of angularly deflected laser beams with a predetermined intensity profile are also described.
