Ophir Optics to Demo Series of New Lenses for Use With High-Power Fiber Lasers at LASER World of PHOTONICS

Ophir Optics, a leading designer and manufacturer of precision infrared and laser optics, have developed a series of new collimating lenses, focusing lenses and protective windows for use with high-power fiber lasers that will help avoid thermal lensing and focus shift.

 

 

Ophir Optics will be demonstrating the ‘Fiberlens’ series at the LASER World of PHOTONICS Exposition 2015 in Munich from June 22 - 25.

The Fiberlens series, which is designed for use with high-power fiber and disk lasers, feature extremely low absorption fused silica substrates and high laser-damage-threshold, and long-lifetime, low-absorption anti-reflection coatings on the lenses and windows.

This means absorption of the Fiberlens is extremely low at < 50 parts per million (ppm), helping avoid phenomena such as thermal lensing and focus shift, which otherwise could degrade cutting quality and cutting speed, and ensuring the highest cutting quality when using multi-kilowatt fiber, disk, and YAG lasers.

To guarantee the high quality and low absorption in its one micron laser optics, Ophir Optics is using a PRIMES Optical Quality Monitor (OQM) to measure the absorption rate of its lenses and windows. The OQM, which measures the temperature rise of the optics when exposed to one micron laser radiation, can reliably and accurately measure extremely low absorption levels.

Ophir Optics will also demonstrate its improved High Reflection (HR) laser mirror coating, which was developed for use in high-power CO2 laser resonators and beam delivery systems. It offers superior performance for cavity optics, reflecting >99.9% for maximum laser energy and enabling S-polarization locking.

The use of coatings like High Reflection (HR) is a cost-effective way to maximise reflection, improve performance with high durability mirror surfaces, and prolong product life while delivering superior cutting quality. Ophir’s OEM-approved HR coating delivers higher reflection than standard coatings at CO2 laser 10.6 micron wavelength.

Demonstrations of Fiberlens will take place at LASER World of PHOTONICS Exposition 2015 in Munich from June 22 - 25. Ophir Optics can found at booth 319, Hall B3.
