2021 High quality 3-5um - KTP Crystal – Dien

Gallium Selenide (GaSe) non-linear optical single crystal, combining a large non-linear coefficient, a high damage threshold and a wide transparency range. It is a is very suitable material for SHG in the mid-IR. The frequency-doubling properties of GaSe were studied in the wavelength range between 6.0 µm and 12.0 µm. GaSe has been successfully used for efficient SHG of CO2 laser (up to 9% conversion); for SHG of pulsed CO, CO2 and chemical DF-laser (l = 2.36 µm) radiation; upconversion of CO...
High Quality High Damaged Threshold Laser Crystals - Rochon Polarizer – Dien

Rochon Prisms split an arbitrarily polarized input beam into two orthogonally polarized output beams. The ordinary ray remains on the same optical axis as the input beam, while the extraordinary ray deviates by an angle, which depends on the wavelength of the light and the material of the prism (see the Beam Deviation graphs in the table to the right). The output beams have a high polarization extinction ratio of >10 000:1 for the MgF2 prism and >100 000:1 for the a-BBO prism. Feature：...

China Gold Supplier for Bandpass Interference Filter - Er:YAP Crystals – Dien

Yttrium aluminium oxide YAlO3 (YAP) is an attractive laser host for erbium ions due to its natural birefringence combined with good thermal and mechanical properties similar to those of YAG. Er:YAP crystals with high doping concentration of Er3+ ions are typically used for lasing at 2,73 microns. Low-doped Er:YAP laser crystals are used for of the eye-safe radiation at 1,66 microns by in-band pumping with semiconductor laser diodes at 1,5 microns. The advantage of such a scheme is low thermal...
Leading Manufacturer for Erbium Yag - Glan Taylor Polarizer – Dien

Glan Taylor polarizer is made of two same birefringent material prisms that are assembled with an air space.Its length to aperture ratio which is less than 1.0 makes it a relatively thin polarizer.The polarizer with no side escape windows is suitable for low to medium power application where the side rejected beams are not required .The angular field of different materials of polarizers is listed below for comparison. Feature： Air-spaced Close to Brewster’s Angle Cutting High Polariza...
