Lasers for Lithography

Lithography is the transfer of a designed pattern onto a flat surface, either directly or via an intermediate medium - excluding areas of the surface where the pattern is not required. In photomask lithography, where a design is patterned onto a substrate, a laser is used to expose the pattern, allowing deposited material to be etched away, preparing it for further processing. This lithography met

Precision Microwave Generation

In the last years the demand for ultra-low noise microwave (MW) and radio-frequency (RF) signal sources have gained more and more importance. Standard industrial applications and high-end academic experiments require ever higher precision: Radar systems Defence communications Photonic ADC Ultra-stable clocking Test and measurement Satellite communications Particle accelerators, FELs Coherent commu

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

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

Optimizing Laser Glass Cutting with Diffractive Beam Shaping

Laser glass cutting with ultra-short IR pulses is lately growing to become a key technique for the high throughput glass processing. Cutting thick glasses (500um) using this technique possess unique challenges, as the laser energy needs to be both foc

Spectral Fiber Sensors for Cancer Diagnostics

Cancer is one of the main causes of morbidity and mortality across the globe. Hence, attempts are focused on the early-stage detection of cancer, and optical spectroscopy has been largely used for early diagnosis of cancer. Fluorescence or molecular

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/

Basics of Beam Expander

The laser beam enter a beam expander after the laser beam is generated in the laser resonator. The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The inp

First Pulsing Control of AO Q-switch Drivers

When Q-Switching lasers at high repetition rates, it is normal to observe a giant first pulse after a pause in operation. For many applications this excess energy must be dissipated before or during the next modulation cycle. For example, in lasermarkers, when the time taken for the scan

Basics of F-theta Lenses

General information Lenses used in combination with XY galvanometer scanners are called -theta lenses, plane field objectives or simply scan lenses. -theta lenses are used in various applications from industrial material processing, drilling, welding

The manipulation of Rb atoms is commonly performed using diode-based laser systems typically producing several hundred mW of usable 780nm power. Many atom optics applications however favour higher laser power whilst maintaining a narrow linewidth and

[Application] Medical Device Manufacturing with FCPA

Lasers are often integral to the production of components for a range of application areas, including medical device manufacturing. These parts are then integrated in numerous products that vary from complex surgical instrumentation to simple single-use products that are used at the time of need by caregivers in hospital settings or out in communities. Designers and manufacturers of medical device

[Application] DOEs for Beam Shaping

A diffractive optical element (DOE) uses thin micro-structure patterns to alter the phase of the light that is propagated through it. Those micro-structures, once properly designed, can manipulate the light to almost any desired intensity profile or s
