Handheld, Low-Level Laser Apparatuses and Methods for Low-Level Laser Beam Production

摘要

A handheld, low-level laser apparatus includes a laser diode configured to generate a laser emission having an astigmatism. The apparatus further includes one or more corrective lens configured alone or in combination to correct the astigmatism and to collimate the laser emission, a divergence lens configured to diverge the laser emission after the laser emission passes through the one or more corrective lens, and a front lens configured to collimate the laser emission after the laser emission passes through the divergence lens. A low-level laser beam producing method includes repeatedly directing an IR laser emission through a series of lenses during a first set of time periods and repeatedly directing a visible laser emission through the series of lenses during a second set of time periods, each time period of the first set of time periods being distinct from each time period of the second set of time periods.

1. A handheld, low-level laser apparatus comprising:
a laser diode configured to generate a near infrared (NIR) laser emission having an astigmatism and propagating along a laser path; one or more corrective lens positioned in the laser path and configured to receive the NIR laser emission therethrough, the one or more corrective lens being further configured alone or in combination to correct the astigmatism of the NIR laser emission and to collimate the NIR laser emission; a divergence lens positioned in the laser path after the one or more corrective lens and configured to receive the NIR laser emission therethrough and to diverge the NIR laser emission after the NIR laser emission passes through the one or more corrective lens; and a front lens positioned in the laser path after the divergence lens and configured to receive the NIR laser emission therethrough and to collimate the NIR laser emission after the NIR laser emission passes through the divergence lens.
