The world's leading platform for in vitro diagnostics

LASER World of PHOTONICS CHINA, Asia’s largest trade fair for the photonics industry, has taken place in Shanghai every year since 2006. It presents the entire range of photonics in an international setting, tailored to the specific needs of the Chinese market.

What are Diode Pumped Solid State (DPSS) Lasers? Diode Pumped Solid State (DPSS) Lasers are solid-state lasers pumped with laser diodes.

For commercially sold lasers and laser systems, it is common to have a set of laser specifications, descriptions of their properties with some precision. Such specifications (in short: specs) are made by suppliers of lasers (usually by the manufacturers), but a buyer also will usually write down the required specifications for his application before selecting lasers.

The 25th China International Optoelectronic Exposition (CIOE) will be held from September 11 to 13, 2024, at the Shenzhen World Exhibition and Convention Center. As a comprehensive exhibition covering the entire optoelectronics industry chain, CIOE brings together over 3,700 high-quality exhibitors from more than 30 countries and regions worldwide.

Laser beams are often close to Gaussian beams, where the transverse profile of the optical intensity can be described with a Gaussian function, the width of which varies along the propagation direction.

Laser diodes are commonly referred to as edge emitting laser diodes because the laser light is emitted from the edge of the substrate. The light emitting region of the laser diode is commonly called the emitter. The emitter size and the number of emitters determine output power and beam quality of a laser diode.

The output wavelength of a laser depends on the laser material, the process of stimulated emission, the optics of the laser resonator, and additional optical components outside the resonator (e.g., non-linear crystals for 2nd, 3rd, 4th, or 5th harmonic generation).

A solid-state laser consists of a gain medium that is a solid, rather than a liquid as used in dye lasers or the gas that’s in a gas laser. The gain medium of a solid-state laser consists of a glass or crystalline host material
