Helium-neonlaserspectrum

The Helium-Neon (He-Ne) laser is a type of gas laser that has been widely used for various applications due to its coherent and monochromatic output. This article explores the construction, working principle, applications, and energy level diagram of the He-Ne laser in detail.

Optical Cavity: The mirrors at the ends of the tube create an optical cavity. Photons generated by stimulated emission bounce back and forth between the mirrors, amplifying and aligning into a coherent beam of light that exits through the partially transparent mirror.

Mirrors: The ends of the laser tube have two mirrors – one highly reflective (HR mirror) and the other partially transparent (output coupler). These mirrors form an optical cavity, providing the feedback necessary for laser action.

Cylindrical microlens arrays are used for the transformation of high power diode laser beams. The INGENERIC micro-cylindrical arrays stand out due to an aberration free image and an optimum light efficiency. Assuring facts for these features are the extremely high pitch-repeatability and the minimized dead-zones between the lens elements. Due to the high form accuracy the arrays show an extremely stable focus position.

He Ne laserfrequency

Stimulated Emission: Photons collide with excited atoms, stimulating the emission of additional photons with the same energy, phase, and direction. This process leads to the generation of coherent light.

The energy level diagram of a He-Ne laser illustrates the energy levels of helium and neon atoms involved in the lasing process. It typically includes the ground state, excited states, and the energy levels corresponding to the laser transition. The specific energy levels are dependent on the characteristics of the helium and neon atoms in the laser tube. The transition from higher to lower energy states corresponds to the emission of laser light, contributing to the coherent output of the He-Ne laser.

Gas Tube: The laser tube is a sealed glass container filled with a mixture of helium and neon gases. The tube is carefully constructed to maintain the purity of the gas mixture.

Gas Excitation: High voltage applied to the electrodes excites the helium atoms, causing electrons to move to higher energy levels. These excited helium atoms then transfer their energy to neon atoms.

Medical Instruments: Used in medical equipment, such as blood flow meters, for their ability to produce a stable and visible beam.

Most spherical and aspherical microlens arrays are customized solutions, especially designed and manufactured for the individual needs of our customers. We manage to manufacture microlens arrays with the following typical characteristics:

Bar Code Scanners: Older generations of bar code scanners utilized He-Ne lasers for their coherent output, which is suitable for barcode scanning applications.

Alignment Tasks: Preferred for precision alignment in industries and research environments owing to their visible and coherent light.
