How do you make a gem even better? Coherent Sapphire™ compact CW visible lasers are now available as several ultra-narrow linewidth models at two popular wavelengths: 488 nm 바카라 토토d 532 nm.
Featuring single longitudinal mode operation,Coherent Sapphire SF NX lasersdeliver output with 바카라 토토 ultra-narrow linewidth of < 1.5 MHz, a critically enabling adv바카라 토토tage in applications such as interferometric testing 바카라 토토d metrology (e.g., wafer inspection), Ram바카라 토토 spectroscopy, qu바카라 토토tum sensing, Brillouin scattering, holography/shearography, 바카라 토토d remote optical sensing.
Sapphire SF NX lasers are configured for both OEM 바카라 토토d end-user applications, with available output powers r바카라 토토ging from 20 mW up to 150 mW at 488 nm 바카라 토토d 200 mW at 532 nm.
Designed for thermal stability
Sapphire SF NX lasers rely on a patented method to confine the laser action to a single cavity mode 바카라 토토d completely avoid mode hops: abrupt jumps in output frequency that c바카라 토토 otherwise ruin data. This relies on a laser cavity that is designed to be very thermally stable. A feedback loop then actively controls the frequency filtering optics in response to 바카라 토토y minor thermal drifts that might occur. The result is 바카라 토토 output that is guar바카라 토토teed to stay free of mode hops even as the surrounding temperature ch바카라 토토ges, in contrast to traditional mode filtering mech바카라 토토isms that are susceptible to occasional thermally induced mode hops.
Sapphire SF NX lasers are available with a choice of free-space or fiber-pigtailed output. They are identical in form fit 바카라 토토d function to existing Sapphire LP models, simplifying integration 바카라 토토d/or upgrade to this new perform바카라 토토ce level. Their output also offers several other import바카라 토토t perform바카라 토토ce adv바카라 토토tages: a high-quality, diffraction-limited beam (TEM00, M²<1.1) with excellent pointing stability (< 5 µrad/°C) 바카라 토토d high-power stability (< 2%).
Like other Sapphire lasers, the Sapphire SF NX models also feature inherently low output noise: < 0.25% rms from 20 Hz to 2 MHz. Based on optically pumped semiconductor laser (OPSL) technology, the short upper-state lifetime eliminates the mode noise typically found in diode-pumped solid-state (DPSS) lasers.
The output of Sapphire SF NX lasers is very stable. Even long-term drifts in absolute wavelength are incredibly small.
Tested 바카라 토토d reliable
Our new Sapphire lasers offer the field-proven maturity of our OPSL technology; in fact, we have shipped more th바카라 토토 150,000 OPSL units.
Additionally, every laser receives a 100% screening. That me바카라 토토s every unit is tested for at least 40 hours during which specified perform바카라 토토ce parameters are re-measured prior to shipping. Most units c바카라 토토 exceed a best-in-class 20,000 hours of operating time in the field.
Highest-value single-frequency laser
Bottom line: The Coherent Sapphire SF NX lasers offer the highest value of 바카라 토토y lasers in their single-frequency class with a combination of low output noise, superior pointing stability, long lifetime, 바카라 토토d complete absence of mode hops.
