Laser cuttings - Import export

With a versatile punch/ laser combination service, Alpha are able to offer complete flexibility to produce punch details such as louvres and ribs alongside complex lasered profiles and etches in one process. The benefits of Punch/ Laser combination are that production time is dramatically reduced by combining the two processes. Costs savings are also made as complex and costly tooling is not required.

Utilising the latest in Fibre Laser Cutting technology Alpha Manufacturing are able to offer a versatile laser cutting service in various material types including; Mild Steel, Coated Steels, Stainless Steel, Aluminium, Wood and Plastics. We currently operate one Co2 Bystronic Laser, one Bystronic BySprintFiber 4020 machine and our latest addition to our Laser service, the Trumpf Trulaser 3030 fibre machine. Fibre optic laser is the latest technology in laser cutting, with complete accuracy and ultra high-speed cutting (whilst also using fewer power resources than traditional lasers, meaning reduced costs to the customer).

Knight Optical’s Laser Optics range include Thin Film Polarisers which separate the s- and p-polarised light with negligible absorbance within the coating for low loss performance. The laser thin film polarisers are optimised for 515nm and 1030nm design wavelengths, ideal for Ytterbium (Yb) doped lasers including diode-pumped solid-state lasers (DPSSL) and fiber lasers, as well as Nd:YAG lasers emitting at 1064nm. Currently, we stock thin film polarisers which work at either 45° or at Brewster angle (55.4°), both of which have been coated using ion beam sputtered (IBS) technology, creating a compact and durable coating, with a LIDT suited for ultrafast laser applications. Often used within a laser resonator to separate the different polarisation states and can be used as an alternative to polarising beamsplitter cubes or Glan-type polarising prisms. The following are the tolerances for the laser polarisers:

As well as Knight Optical’s Low GDD Ultrafast Laser Mirrors, we can also provide broadband and wide-angle alternatives to cover more of a range of applications. Our Wide-Angle Laser Mirrors optimised for the fundamental and second harmonic (SHG) emissions of Ytterbium (Yb) doped lasers including diode-pumped solid-state (DPSS) and fiber lasers, and therefore have a design wavelength of either 515nm or 1030nm. They exhibit > 99.9% reflection when used between 0 to 45°. The Broadband Laser Mirrors work from 700-900nm ideal for applications using a Ti:Sapphire laser, again demonstrating > 99.9% reflection within this wavelength range. Their key features include: •Ion beam sputtered (IBS) coating which is compact and durable. •Reflection > 99.9% within their design wavelength range. •Broadband laser mirrors work at 45° •Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening •High laser induced damage threshold (LIDT) •Precision flatness and surface quality to
