摘要： A high-power flowing-gas laser comprises a laser channel folded to include at least two legs angularly disposed to each other in a common plane and having a single folding mirror between them such that the laser rays through one leg, on the upstream side thereof with respect to the gas flowing transversely across that leg, are reflected by the folding mirror so as to be transposed to the downstream side of the other leg with respect to the gas flowing transversely across the other leg. A number of embodiments are described wherein the laser channel is folded to include four or other even number of legs according to a polygonal configuration, there being a separate flowing gas channel for each leg, all the gas channels directing the gas flow radially inwardly to a common collection region. Among the advantages provided by the described constructions are compensation for phase distortion and amplitude variations, and maximum laser channel length and laser output for a given system size and volume.

摘要： A spherical laser includes a transparent or semi-transparent outer spherical vessel having an internal cavity, an amplifying medium in the cavity, and means to excite the amplifying medium. The sphere is provided with a partially reflective coating to act as a spherical optical resonator. Excitation of the amplifying medium produces an optical gain. When the gain exceeds cavity losses and threshold conditions are met, lasing is supported. This creates a three-dimensional, spherically radiating emission, emulating a point source. The output is radially diverging, but is harnessed by enclosing the sphere within a mirrored ellipse to image the output to a point, or within a mirrored parabola to columinate the emission. A concentric, reflective inner sphere may be disposed in the cavity, with the amplifying medium lying between the two spheres. A voltage potential is applied between the spheres to excite the medium.

摘要： The present invention generally relates to lasers comprising fluidic channels, such as microfluidic channels. In some instances, the channel contains two or more fluids. The fluids may remain non-mixed within the channel, for example, due to immiscibility and/or laminar flow within the channel. The fluids may be arranged in the channel such that light propagating in a first fluid is prevented by the second fluid from exiting the first fluid, for example, due to differences in the indexes of refraction (e.g., causing internal reflection of the fluid to occur). Thus, in one embodiment, a first fluid may be at least partially surrounded by a second fluid having a second index of refraction lower than the index of refraction of the first fluid. In some embodiments, the fluidic channel is used as a laser, for instance, a dye laser, i.e., a laser created by directing light at a dye to produce coherent light. The dye may be present in one or more fluids within the fluidic channel. The incident light (for example, created by another laser) may be directed at the channel from any angle. In some cases, laser light may be produced in a direction substantially aligned with the longitudinal axis of the channel. In some embodiments, the laser is free of mirrors, prisms, or gratings, or the laser may produce coherent light using a non-resonant photonic pathway. However, in other cases, mirrors, prisms, or gratings may be used to reflect light along the channel to enhance stimulated emission of coherent light. Another aspect of the invention includes optical diffractors, such as prisms or gratings, which can contain a fluid. The optical diffractors, in certain embodiments, are positioned to diffract light, such as coherent light, emanating from the fluidic channel. Still other aspects of the invention provide devices, kits, and methods of making and using such lasers.
摘要翻译：本发明一般涉及包括流体通道的激光器，例如微流体通道。在一些情况下，通道包含两种或更多种流体。流体可以在通道内保持不混合，例如，由于通道内的不混溶和/或层流。流体可以布置在通道中，使得通过第二流体从第一流体中排出的光例如由于折射率的差异（例如，引起流体的内部反射）而被阻止在第一流体中传播的光）。因此，在一个实施例中，第一流体可以至少部分地被具有低于第一流体的折射率的第二折射率的第二流体包围。在一些实施例中，流体通道用作激光器，例如染料激光器，即通过在染料处引导光以产生相干光而产生的激光。染料可存在于流体通道内的一种或多种流体中。入射光（例如，由另一激光产生的）可以从任何角度指向通道。在一些情况下，可以在与通道的纵向轴线基本对准的方向上产生激光。在一些实施例中，激光器不含镜子，棱镜或光栅，或者激光可以使用非共振光子通道产生相干光。然而，在其他情况下，可以使用反射镜，棱镜或光栅来沿着通道反射光以增强相干光的受激发射。本发明的另一方面包括可以包含流体的光学衍射器，例如棱镜或光栅。在某些实施例中，光衍射器被定位成衍射从流体通道发出的光，例如相干光。本发明的其它方面提供了制造和使用这种激光器的装置，套件和方法。
