High homogeneity & Super large size ZnGeP2 crystals

25×25×30mm is demonstrated as the alternative perfect choice for high power middle infrared.

Compared to traditional ZGP( 6×6mm)crystals, DIEN TECH's 25×25mm ZGP crystal has achieved a leap forward in multiple core indicators through precision polishing and unique processes and formula while retaining its large-size.

Background

In the past a few years, ZnGeP2 crystal was challenged by size beyond 6mm width/high and maintain good homogeneity at the same time.DIEN TECH’s new developed YS-ZGP crystal (25×25mm) has shattered the long-standing performance limitations of conventional ZGP crystals (6×6mm) in the industry. Boasting core advantages of high uniformity and low absorption, this innovation represents a pivotal breakthrough for the industry.

Homogeneity

Upper two crystals are in size 6x6x20mm and down one is in size 25x25x30mm. Material absorption is significantly reduced,even at a size of 25×25mm. Through infrared camera, DIENTECH ‘s shows its outstanding advantage. And this properties also proved can generating higher conversion efficiency.

Low Absorption

See above transmisson measure data in short wavelength before 1 micrometer and see below interferometer measurement confirm that refractive index deviation is controlled within an extremely narrow range, far exceeding the conventional standards of ZGP( 6×6mm)crystals This ensures beam transmission stability is enhanced significantly.

This cutting edge technology is a milestone for high power and high efficiency middle infrared OPO and OPA system. Not only addresses the urgent demand for large-sized crystals in high-power laser applications but also redefines industry standards for ZGP crystals with its "large yet precise" performance profile, offering an innovative and fundamental solution to the industry.
