Laser Crystals | EKSMA OPTICS

Features & Benefits:

Laser Gain Medium: Laser crystals serve as the gain medium where population inversion occurs, leading to laser amplification.
High Optical Quality: Laser crystals are carefully engineered to have high optical quality, ensuring minimal optical losses and beam distortion.
Tunable Wavelengths: Different laser crystals have specific emission wavelengths, allowing for tunability across various parts of the electromagnetic spectrum.
Efficient Pumping: Laser crystals are designed to efficiently absorb pump energy, which is then used to amplify the laser beam.
Temperature Stability: Some laser crystals offer good temperature stability, allowing for continuous and stable laser operation.
