Photonics Industries (PI), The Pioneer of Intracavity Solid-State Harmonic Lasers, has increased the pulse energy of its DSH Series UV ns laser to >1mJ
Photonics Industries has released a UV nanosecond laser (the DSH-355-25) that delivers up to 30W of intracavity harmonic average power at 355nm from a compact, rugged, monolithic laser head.
Photonics Industries’s patented intracavity UV generation is based on non-consumable THG crystals with no crystal indexing required. It allows for a simpler optical resonator for better stability, insensitive to ambient temperature changes. The more efficient harmonic conversions enables lighter weight/smaller form factor laser heads that can be mounted on movable platforms.
