Optical Isolator

An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity. The operation of the dev

Fiber Laser Basics

A fiber laser (or fibre lase) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing. A fiber laser with MOPA configuration is shown as follows: Pump laser diode: Fiber-coupled diodes

Choosing the Right Galvanometer and Servo for the Job

Galvanometer-based optical scanners are the preferred positioning solution for an increasingly broad range of industrial, scientific, imaging, and medical laser applications. While a number of scanning approaches are available, galvanometer-based scanners commonly called galvos offer flexibility, speed and accuracy at an attractive cost. While many imaging applications take advantage of the galvos

The Ongoing Development of Engineering Talent at G&H Ilminster

Earlier this month, GH Ilminster coating supervisor Mark Long was awarded his accreditation certificate after completing the Sharing in Growth Lighthouse Team Leader Academy course. The Sharing in Growth (SiG) run course aims to develop highly talented leadership to meet current and future manufacturing needs. As part of the course students travel to Toyota UK to experience world class manufacturi

New Ultra Compact Made-to-order Single-SLD Light Sources

Superlum starts offering new ultra compact made-to-order single SLD light sources, SLD-uCS series. The SLD-uCS is a miniaturized version of the SLD-mCS with half the footprint. It has the same I/O and connectors and requires the same input voltages, thus allowing easy replacement of SLD-mCS sources in applications were the system size becomes of critical importance. SLD-uCS sources may be build ba

Laser Engraving

Laser engraving, which is a subset of laser marking is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which also includes color change due to chemical/

How to Select An Electro-optic Q-switch (Pockels Cell)

1. How to Select an EO Q-switch to Meet Your Switching Frequency Requirement The simple answer is that the IMPACT Pockels cells are recommended for operation at a maximum of 1-2kHz. This is not to say they will completely fail to operate at 5kHz. The
