1. Laser Power / Energy Measurement Today
   11/11/2011
   While the laser industry is steadily advancing, with new wavelengths, higher powers and energies, and new applications, the basic technology of laser power/energy measurement has not changed in the last 10 years. There are still three basic ways to measure laser power and energy: thermopile detector, photodiode detector, and pyroelectric detector. By Dr. Ephraim Greenfield, CTO, Ophir Optronics
2. Application Note: Energy-Efficient, Process-Reliable Mass Production Of Thermoplastic Automotive Components
   9/20/2010
   Industrial series production of very large quantities of automotive components at one of Germany's largest automotive suppliers is a challenge. By Peter Bruns, Manager of Application & Technical Service, LIMO Lissotschenko Mikrooptik GmbH
3. Application Note: High Power All-In-Fiber Linearly Polarized Laser Using Chiral Grating-Based Polarizer
   8/3/2010
   Different products are available on the market and previous works have demonstrated other methods to obtain linearly polarized fibre lasers. A well-known method consists in using narrow linewidth cross-matched Fibre Bragg Gratings (FBG) for polarization selection; others are based on integrating a polarization dependent loss element into the fibre laser cavity. This can be, for instance, a tilted FBG, a large mode area coiled fibre, or a polarizing photonic crystal fibre. In this letter we use a new Chiral Grating based Polarizer (CGP).
4. Expanding Markets On A Miniature Scale
   7/27/2010
   Components made from alumina (Al2O3), silicon nitride (Si3N4), aluminum nitride (AlN) and other ceramic materials are used in a wide range of electronic, automotive, aerospace, medical, and other high-tech applications. As these application areas continue to grow, manufacturers must find new and better solutions for machining these materials so that they can produce parts more cost effectively and on an increasingly smaller scale. While lasers have been used to drill, cut, and scribe ceramics for many years, the latest generation of laser systems offers new micromachining possibilities in ceramics.

6. An Introduction To Optical Parametric Oscillators
   7/6/2010
   Unlike a tunable laser, which employs various energy strategies to deliver relatively broad coverage, an optical parametric oscillator (OPO), in a process similar to harmonic generation, relies on the nonlinear response of a medium to a driving field (the pump laser beam) to convert photons of one wavelength to photons of other, longer wavelengths.
