A method of transferring energy in an optical fiber () from the fiber's cladding element () of the fiber's core element () is disclosed. The core element () includes an active gain component and an energy migration component, and the cladding element (), which surrounds the core element (), includes the energy migration component. The method includes the steps of providing a pump () for producting energy and optically coupling the pump with the cladding element (), such that the energy is absorbed and stored in the cladding element () by its energy migration component. A further step includes the active gain component in the core element () lasing or providing gain, when the transferring of energy from the cladding element's energy migration component to the core element's energy migration component takes place.

Fiber laser with cladding-to-core energy migration

A method of transferring energy in an optical fiber structure is disclosed. This method transfers energy from a cladding element of the fiber structure to a core element of the fiber structure. The core element includes an active gain component and an energy migration component. The cladding element, which surrounds the core element, includes the energy migration component. The structure and method can be utilized to provide either an optical fiber laser or an optical fiber amplifier. The method includes the steps of providing a pump for producing the energy and optically coupling the pump with the cladding element. The cladding element, including the energy migration component, is then pumped with the energy produced by the pump such that the energy is absorbed and stored in the cladding element by the energy migration component. The method further includes the step of transferring the energy stored in the cladding element to the core element by migration of the energy within the energy migration component to the active gain component such that the active gain component in the core element lases or provides gain.

A high-gain phosphate glass composition, which can be used to produce ultra-short gain length lasers and optical amplifiers is described wherein the composition of the glass in addition to exhibiting high gain for lasers and amplifiers, also exhibits high thermal shock resistance, high cross section, insignificant concentration quenching, and high solubility for rare earth ions and other properties which enable the material to be fabricated into a new class of ultra-short length micro-laser, fiber laser and amplifier configurations and designs.

An optical fiber laser structure and system are disclosed. The fiber laser structure includes a core, an inner cladding, and an outer cladding. The core has a first and second end and includes a combination of ytterbium and erbium as a first active gain component. The inner cladding, having a length defined between the first and second ends, surrounds the core. The inner cladding includes neodymium as a second active gain component that is different from the first active gain component. The system includes a pumping source coupled to the inner cladding to provide energy to the neodymium in the inner cladding. Upon being pumped, the neodymium achieves amplified spontaneous emission in the inner cladding along the length between the first and second ends. As a result, energy is efficiently transferred from the neodymium to the combination of the ytterbium and erbium in the core thereby providing laser activity at an eye-safe laser wavelength of 1535 nanometers.

A method of ablating non-metallic dental material from a tooth comprises the steps of generating radiation pulses having a predetermined wavelength, energy level, pulse repetition rate, and duration, and applying the radiation pulses to the non-metallic dental material in a tooth, whereby the non-metallic dental material is ablated from the tooth. The radiation may be generated by a frequency tripled Nd:YAG, an Er:YAG laser or an Er:YsGG laser and may have a wavelength of about 355 nanometers, 2.94 micrometers, and 2.79 micrometers respectively, for example.

A dental laser apparatus and method is disclosed for removing tooth decay. A substance which selectively attaches to tooth decay is applied to the tooth. This substance has a predetermined absorption band. A laser having an output wavelength which corresponds to the absorption band is supplied and is absorbed primarily by the decayed portions of the tooth. The use of Acid Red 52 dye or basic fuchsin as the substance and a frequency doubled Nd:YAG, Argon or other laser as the source is disclosed as one embodiment.
