Discover our range of technologies
Diode-pumped solid-state (DPSS) lasers are solid-state lasers made by pumping a solid gain medium, for example, a ruby or a neodymium-doped yttrium aluminium garnet (YAG) crystal, with a laser diode. Our high-performance DPSS lasers provide consistent results for spectrum analysis, interference, measurement, holography, laser printing, chip inspection, collimation, laser medical treatment, scientific experiment, and other applications. Our range of DPSS lasers features excellent sealing and high output power stability, operating at a wide range of temperatures.
The narrow optical bandwidth of diode lasers makes it possible to pump directly certain transitions of laser-active ions without losing power in other spectral regions, contributing to high efficiency. The low-intensity noise of laser diodes leads to the low noise of the diode-pumped laser whilst the compactness of the pump source, the power supply, and the cooling arrangement makes the whole industrial laser system much smaller and easier to use. DPSS lasers are idea across a range of industries and applications including:
- Data storage
- Laser Spectroscopy
Gas lasers may sound like old technology, but they are still the solution of choice for many applications such as He-Ne lasers, largely replaced today by diode lasers, are still the best choice for some scientific uses due to its very high coherence length that can vary from 20cm (for multiple longitudinal modes) up to 100m (depending on its cavity design). Another example is CO2 lasers, largely replaced today by fibre lasers in the industry for material processing, which are still the best choice for some applications depending on the type of machined material. This is due to the unique properties of its wavelength of typically 10.6µ vs shorter wavelength around 1.06µ for equivalent high power continuous fibre and industrial lasers.
High-speed laser illumination
For image and video recording of fast processes in industry and research, supporting illumination sources are necessary for guaranteeing the high-quality required for your high-speed camera solution. Additional illumination allows the camera to select shorter exposure times and thus automatically leads to faster frame rates in the so-called high-speed range of several thousand to millions of frames per second. In addition to classic halogen lamps and powerful LEDs, laser illumination offers additional advantages because it operates in very short pulses down to 1 ns and can therefore massively reduce disturbing motion blur. Monochromatic laser illumination with high spectral intensity can even make objects and processes visible that usually dazzle the camera with strong process light. Examples include high contrast visualisation of molten pools during welding, cutting, or modern additive production processes (3D printing).
- High-speed laser illumination allows shorter exposure times and faster frame rates
- Noticeable reduction of disturbing motion blur due to 1 ns short laser flashes
- Visualisation of hidden fast processes (spectral process light suppression)
