High Quality Laser Krypton Lamp for Fiber Laser Cutting Machine

Krypton lamp
Krypton lamps are the pump light sources for solid-state lasers . Because the luminescence spectrum matches the absorption band of YAG:Nd+3 crystal, and the relative light energy utilization ratio is relatively high, it is the most important YAG continuous solid-state laser optical pump light source.

Basic Parameters
Working Substance
Filled gas: High-purity krypton gas (purity usually ≥99.99%). Some special-purpose krypton lamps may be mixed with other inert gases (such as argon) to optimize performance.
Lamp Type and Structure
Common types: Pulsed krypton lamps, continuous krypton lamps, long-arc krypton lamps, short-arc krypton lamps, etc. The structure includes a quartz glass envelope, electrodes (tungsten electrodes), leads, etc.
Dimensions: Depending on the application, the length ranges from a few centimeters to dozens of centimeters, and the tube diameter is approximately 5–20 mm.

Photoelectric Parameters
Spectral Characteristics
Emission spectrum: Mainly concentrated in the infrared, visible, and ultraviolet bands, with characteristic spectral lines including:
Infrared region: 750 nm, 766.5 nm, 794.8 nm, etc.
Visible region: 482 nm, 530.9 nm, 557 nm, 647.1 nm (red light, the strongest spectral line), etc.
Ultraviolet region: Below 350 nm (with lower intensity).
Spectral distribution characteristics: A combination of continuous and line spectra, with energy concentrated in the red and near-infrared regions. It is suitable as a red light source or a laser pumping source (e.g., pumping ruby lasers).

Power and Energy
Continuous krypton lamps: The power range is typically from tens of watts to several kilowatts, with typical values such as 100 W, 500 W, and 1000 W. The luminous efficiency is about 20–40 lm/W (visible light efficiency).
Pulsed krypton lamps: The single-pulse energy can reach tens to thousands of joules, the pulse width is generally 0.1–10 ms, and the repetition frequency can range from a few Hz to tens of Hz (depending on cooling conditions).
