摘要：
A laser femtosecond microtome for cutting out by a focused laser beam at least one slice of material in a material block, wherein the block includes a front surface and the slice carrying the front surface, the slice extends at least partially substantially in a X, Z plane perpendicular to an axis Y of the block thickness, the slice is separated from the remaining part of the block by a cleavage surface formed by an assembly of bubbles brought together, each bubble is formed in a focus area of at least one convergent laser beam pulse of an optical axis L. According to the invention, the optical axis L of the convergent part (3) of the laser beam forms an angle ranging between −45° and ±45° relative to the X, Z. The ellipsoid-shaped focus area has its smaller axis in the direction of the axis Y.
摘要（中）：
一种激光飞秒切片机，用于通过聚焦激光束切割材料块中的至少一片材料，其中该块包括前表面和承载前表面的切片，切片至少部分地基本上以X，Z 垂直于块厚度的轴线Y的平面，通过由组合在一起的气泡形成的裂开表面将切片与块的剩余部分分离，每个气泡形成在至少一个会聚激光束的聚焦区域中 光轴L的脉冲。根据本发明，激光束的会聚部分（3）的光轴L相对于X，Z形成在-45度和±45度之间的角度。椭圆形 焦点区域在轴线Y的方向上具有较小的轴。
