PLD

Using laser ablation on the target surface and depositing the ablated material onto a substrate to form a thin film

Pulsed Laser Deposition (PLD) is a technique that uses a laser to bombard a target material, causing the ejected material to deposit on various substrates, forming coatings or thin films.

OPO Pumping

OPO is the abbreviation for Optical Parametric Oscillator

OPO is the abbreviation for Optical Parametric Oscillator. This technology involves placing a nonlinear medium within an optical resonator, allowing the pump light, signal light, and idler light to pass through the nonlinear medium multiple times. When the gain obtained from parametric amplification of the signal and idler light exceeds their losses within the resonator, laser oscillation is formed in the resonator.

PIV

A non-contact, instantaneous, dynamic, full-field velocity measurement technique

A PIV system mainly comprises four parts: a timing controller, a computer with PIV application software, an image recorder, and an optical illumination system. It uses optical methods to measure flow and study structures within airflow and liquid flow fields, evolving from traditional flow visualization techniques.

Ti:sapphire Pumping

One of the main application directions of solid-state lasers

It uses continuous or pulsed 532nm or 527nm green light to excite the Ti:sapphire crystal, causing particle transitions and generating Ti:sapphire femtosecond laser.

LiDAR

A tool for active remote sensing detection.

Lidar sends short pulses of laser light into the atmosphere, where the laser interacts with substances in the air, producing reflected and scattered echo signals. These signals are collected by a telescope and analyzed to obtain atmospheric parameters.

Laser Ultrasound

The physical process of generating ultrasound in a medium by a pulsed laser or using a laser to produce ultrasound.

Lasers can produce ultrasound in solids, gases, and liquids. Due to the advantages of ultrasound, such as short wavelengths, strong directionality, and the ability to diffract and scatter when encountering obstacles, ultrasound detection technology has been a great method for non-destructive testing, studying material properties, and structural analysis. It is also widely used in medical diagnostics, geological exploration, and construction engineering.
