Long coherence, narrow linewidth DPSS lasers for high resolution hologram production
The Skylark NX series of single frequency C-DPSS lasers provides the ideal combination of high power and pure spectral properties to enable high resolution holography.
Skylark Lasers outperform HeCd gas lasers in holography applications
The Skylark 640 NX and Skylark 532 NX are ideal for holographic applications, reaching the highest output powers available on a compact design.
Our lasers provide excellent beam quality with a TEM00 mode and an M2 factor < 1.2. The long-term wavelength drift of our lasers is < 1 pm with a peak-to-peak power stability of < 1%.
For holographic applications requiring a UV laser source, our 320 NX and 349 NX offer ultra-stable performance at output powers up to 400 mW.
Customers seeking a solid state replacement for 325 nm and 442 nm HeCd lasers have selected our lasers for their higher output power, higher output stability, and greater coherence.
Low noise
Low intensity and phase noise with improved signal-to-noise ratio (SNR) for sharper and more accurate holograms.
High coherence
Enables the creation of large, stable interference patterns and the precise development of big and complex holographic outputs.
Narrow linewidth
Ensures clarity and detail of high resolution holograms with minimal distortion, defects, or blurring.
Ultra-stable output
Ultra-consistent wavelength output and power for reproducible, high-quality holograms without unwanted variations.
What is holography?
n typical holography, the laser beam is split into two, one known as the object beam and the other as the reference beam. The recording medium is located where this light, after being reflected or scattered by the object, will strike it. The reference beam is made to shine directly on the medium, where it interacts with the light coming from the object to create the desired interference pattern.
DPSS lasers are the highest power, spectrally pure light sources for holography
Skylark Lasers offer high power, single frequency laser sources with a coherence length exceeding 100 metres. With long-term power and wavelength stability, our compact lasers at 532 nm and 640 nm are ideal for holography and applications that use holographic techniques:
