High Powered Diode Laser Optics

PowerPhotonic is a pioneer in the use of phase plates to correct for the imperfections in the laser output of a diode bar or diode laser stack. All diode bars and diode bar stacks have imperfections inherent in the manufacturing process or caused by mechanical stress during the assembly process. This can result in errors due to bar smile, de-focus errors typically caused by FAC misalignment or other aberrations caused by defects at the facet of the bar. These imperfections can be either systematic, or variable but in either case can be corrected with an optical phaseplate.

PowerPhotonic has a range of high power diode correction optics, some of which are standard products, and others that can be customised as a result of wavefront analysis. Due to PowerPhotonic’s direct write process, it is economical to manufacture customised correction optics that are individually matched to the diode bar or stack.

PowerPhotonic is supplying a new generation of diode micro-optics for high power laser diode pump sources in the worlds’ most demanding environments.  The novel patented optics, which are manufactured using PowerPhotonic’s unique direct write laser micro-machining technology, have been in development for the last five years at PowerPhotonic. The optical design provides precise beam shaping in an ultra-compact and reliable optic assembly, used to collimate the world’s highest peak-power laser diode arrays. The ultimate home of these new optics is the High Repetition-Rate Advanced Petawatt Laser System (HAPLS), currently being built by Lawrence Livermore National Laboratory (LLNL) for the European Union’s Extreme Light Infrastructure (ELI) facility near Prague, Czech Republic. The HAPLS laser will be capable of delivering laser pulses at a repetition rate of 10 per second, each with peak power of greater than 1 petawatt.  ELI will be the world’s first international laser research centre, operating in a similar manner to the particle physics facility at CERN. The laser facility aims to host some the most intense lasers in the world and make them available to an international scientific user community. – See more at: https://lasers.llnl.gov/news/science-technology
