We numerically model the axial trapping forces within optical tweezers arising from Laguerre–Gaussian laser modes. For an 8 μm diameter sphere suspended in water, the higher-order modes produce an axial trapping force several times larger than tha

Second-harmonic generation has been obtained by the use of Laguerre-Gaussian beams in a variety of mode orders. Each mode becomes doubled in frequency and transformed to a higher order. We show this to be a consequence of the phase-matching condition

We outline an easily reproduced experiment that allows the student to investigate the intensity and phase structure of transverse laser modes. In addition to discussing the usual Hermite–Gaussian laser modes we detail how Laguerre–Gaussian laser

Gonadotrophin releasing hormone analogues (GnRH-A) suppress ovarian activity resulting in lowering of plasma oestrogens and androgens of ovarian origin, thus reducing androgen drive to target organs in the skin. They may be of value in the treatment

The standard configuration for an optical tweezers arrangement uses a fundamental TEM0.0 laser mode as the trapping beam. However, even modest laser powers may result in damage, or “opticution,” of delicate biological samples.
