Ultra-low noise, narrow linewidth DPSS lasers delivering the spectral purity needed to reveal weak and complex Brillouin scattering
Single-frequency diode-pumped solid-state (DPSS) lasers from Skylark Lasers provide highly stable, low noise sources in the UV and NIR with ASE noise < – 80 dB, and passive linewidth < 13 kHz / 1 ms.
High optical power and outstanding spectral purity are critical for enhancing signal strength, especially in samples with weak or complex scattering characteristics. Skylark NX DPSS lasers are specifically engineered to deliver robust performance without the noise, instability, or alignment challenges commonly associated with amplified diode laser systems.
Skylark Lasers outperform market-leaders for Brillouin microscopy applications
Skylark NX lasers combine efficient high power with spectral purity — even at the fiber output. Delivering ultra-stable output with an ultra-narrow linewidth, Skylark NX lasers at 780 nm and 785 nm provide a clean beam with ASE noise < – 80 dB without filters or mode cleaning.
Narrow linewidth
Reduces spectral broadening, leading to sharper Raman peaks, better signal resolution, and SNR.
Ultra-stable output
Ultra-consistent wavelength output and power intensity to reduce measurement fluctuations.
Inherently clean beam
Low noise and spectral purity without filters or mode cleaning.
Long lifetime
Long maintenance-free lifetime to fit into existing spectrometer maintenance schedules.
DPSS lasers deliver the lowest noise and cleanest beams for Brillouin microscopy
Skylark NX lasers provide low ASE noise and clean beams for Brillouin microscopy and spectroscopy applications. Lasers are developed at 780 nm and 785 nm with up to 400 mW output power, and UV wavelengths at 320 nm (up to 200 mW) and 349 nm, with up to 400 mW.
With inherently low noise and narrow linewidth, the lasers have the spectral purity required for precision-demanding Brillouin techniques:
-
Brillouin microscopy
-
Brillouin spectroscopy
-
Stimulated Brillouin-scattering
-
Whispering-gallery-mode (WGM) Brillouin
-
Brillouin cooling
-
Raman-Brillouin hybrid techniques
-
Confocal Brillouin
Energy-efficient, with high power delivered from a compact footprint, Skylark NX DPSS lasers produce minimal heat. This simplifies integration into spectrometers and other Brillouin set-ups.
Skylark NX DPSS lasers offer ultra-stable wavelength and power stability over long operation. The long maintenance-free lifetime of our lasers reduces operational and maintenance costs for manufacturers and end users.
High spectral purity
Single frequency operation combined with an ultra-narrow linewidth delivers improved signal-to-noise ratio (SNR) and resolution of Brillouin measurements.
Reduced noise
The monolithic architecture of Skylark NX lasers minimises laser-induced background interference, to enhance the clarity of Brillouin measurements by several orders of magnitude.
