Understanding Laser Optics 1: The Physics of Lasers
In today’s article from Shalom EO, as the first lesson from the series of understanding laser optics topic, we will begin with the very fundamental physics of lasers, how a laser cavity works.
Dispersion Compensation Chirped Mirrors
Dispersion compensation for ultrafast lasers is to introducing a negative GDD that cancels out the positive GDD that results from chromatic dispersion. Dispersion compensation is critical for femtosecond ultrafast lasers to preserve the temporal profile and peak power of laser pulses. Chirped mirrors are a special dispersive Bragg mirror coated with alternating dielectric thin films of high and low refractive indices, and the thickness of the thin films becomes thinner towards the surface to provide larger group delay dispersion for longer wavelengths.
How ZnS and ZnSe Are Replacing Germanium (Ge) in IR Optics
Due to recent exporting rules, the price of germanium on the global market is surging, and the delivery is much longer than before. Zinc Sulfide (ZnS) and Zinc Selenide (ZnSe) are increasingly used as substitutes for Germanium (Ge) in infrared (IR) optics. This article offers a detailed comparison and explanation of how ZnS and ZnSe are replacing Ge as IR optics in their optical performance, thermal and mechanical properties, and costs.
How to Choose Your Fast Timing Scintillators
In this guidance to fast timing scintillators, Shalom EO will use our professional knowledge to help you learn about how to choose the best fast timing scintillators that suits your uses, by facilitating you to understand what is decay time and its implications in the application senario, and offering detailed explanation of the critical performance parameters that you should consider when selecting your scintillator materials.
High Power Ultrafast Laser Mirrors-You Need to Know
In this article, which is we will be looking at different aspects of ultrafast lasers, including how are ultrafast lasers produced (via mode locking and chirped pulse amplification), the optics needed for a ultrafast femtoline laser setup, the core elements for ultrafast lasers-ultrafast laser, mirrors the technical challenges for ultrafast laser mirrors.
What Are Achromatic Lens Used For
An achromatic lens, often called an achromat, is a lens consisting of more than one carefully engineered lens element combined (often cemented) together, used to minimize chromatic aberration. In this article, we will explain the fundamentals of achromatic lenses, what are achromatic lens used for, the designs of achromts.
Explore 755nm Alexandrite Laser Optics
Alexandrite lasers are laser sources that adopt the alexandrite crystal as the laser gain medium, operating at a wavelength of 755nm, and are among the most versatile and effective laser systems available today. Their unique properties make them essential tools in both medical and aesthetic applications. In this article, we will explore the uses of Alexandrite lasers, compare them with diode lasers, and shed light on the optical components that ensure their optimal performance.
