Application-led laser selection
From resolving a weak Raman line to holding a single cell in place, the application defines the laser. Explore the workflow, identify the critical parameters, then qualify the source with Precisometer.
Application library
01Protect weak molecular fingerprints with a clean, stable excitation line.
02Keep every excitation channel steady while cells move at instrument speed.
03Put the right photons at the sample—channel by channel, scan by scan.
04Turn a seeded flow field into a crisp, time-resolved velocity map.
05Create a quiet, stable trap for forces measured at the nanoscale.
06Address narrow transitions without letting the source become the experiment.
07Convert optical absorption into depth-resolved acoustic contrast.
08Deliver stable UV pulses for repeatable desorption and efficient ionization.
09Feed a tunable ultrafast source with a quiet, high-quality green pump.
10Set the pulse–material interaction to remove, sample, or identify matter.
11Create high-contrast, small-feature marks with less heat in the part.
12Match excitation, delivery, and detection around the light your sample returns.
Precisometer laser request
Include application, wavelength, mode, power or energy, linewidth or pulse width, delivery, control, and safety constraints.
Before you specify
Which specifications actually matter for your experiment, and what happens when the wrong one is optimised.
PhotonicsLinewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.

Optical trappingWhy wavelength is decided by photodamage, focal heating, and detector bandwidth rather than trapping force — and what laser noise costs you in piconewtons.
