HeCd gas laser vs. DPSS laser
Looking to replace your helium cadmium laser with an efficient, high power DPSS laser alternative?
Benefit from up to 4x more usable power, stable and reliable output, and a high quality beam without mode cleaning.
The Skylark 320 NX is designed to replace HeCd lasers in applications across:
- Laser interference lithography
- UV Raman spectroscopy
- Photoluminescence
Upgrade your UV workhorse
Helium Cadmium (HeCd) lasers have long served the demand for ultraviolet wavelengths at 325 nm — but are now outclassed by a diode-pumped solid-state laser alternative.
Upgrading from a 325 nm HeCd to a 320 nm Skylark NX DPSS laser offers four times more power, improved stability, lower maintenance, and a cleaner spectral performance within a compact, solid-state laser platform that is ready for integration into both research and industrial environments. Discover 6 reasons to consider replacing your HeCd system with a DPSS laser on our blog.
Four times more usable power
The Skylark NX 320 nm DPSS laser delivers up to four times the output power of a typical 325 nm HeCd system.
Higher power translates to shorter processing times, higher throughput, and improved signal strength in UV-sensitive materials and processes.
Long term stability
HeCd lasers are prone to power drift and thermal instability, which can affect repeatability and accuracy in precision applications.
The Skylark 320 NX offers wavelength stability of ± 0.2 pm and power stability within ± 2% over 10s of hours, maintaining consistent illumination and spectral performance over extended operation.
Spectral purity
The Skylark NX laser operates in a single frequency, TEM₀₀ mode with M² ≤ 1.2, delivering a clean Gaussian beam and ultra-narrow linewidth: < 1 GHz vs. < 0.00005 GHz.
This produces stable interference fringes, uniform illumination, and excellent spatial coherence, improving feature uniformity in lithography and data quality in spectroscopy.
Low maintenance, compact design
DPSS lasers often have a longer lifetime and double the maintenance interval of gas lasers, significantly reducing downtime and operational disruption. Paired with long-term stability, DPSS lasers also offer increased reliability that makes them ideal for industrial customers seeking to reduce time and resources spent on reactive maintenance.
