Frequency Ultra-stabilized He-Ne Laser｜ MOC LASER (Micro Optics Co.,Ltd.)
Frequency ultra-stabilized He-Ne laser, MOC LASER , achieves 10⁻¹¹-level frequency stability and 0.01 nm measurement accuracy per meter.
Widely adopted as a laser light source for high-precision measurement systems such as lens metrology for smartphone and automotive cameras, flatness measurement of semiconductor wafers, and birefringence evaluation in photomask and stepper exposure equipment.
Over 1,000 units delivered to equipment manufacturers worldwide.
We offer three product variations tailored to different applications and required stabilities:
MOC LASER Products Line-up
| Products | P/N | Main Features |
|---|---|---|
|
YS-307 |
By utilizing the frequency pulling effect, the YS-307 achieves ultra-high frequency stability in the order of 10−11, along with a 3 mW single-mode output. Its high output power makes it well-suited for multi-axis and high-speed interferometric measurements. Furthermore, by mode locking at the center of the neon gain curve, the system ensures excellent frequency repeatability upon reboot. |
 |
QQD |
The QQD model is a transversal Zeeman laser that stabilizes the frequency difference between two orthogonal frequency components generated by a transverse magnetic field.Its orthogonal dual-frequency output can be applied directly to the heterodyne interferometers without any additional devices. |
 |
QS |
The QS model stabilizes the power ratio between two oscillation modes, being provided with either single-mode or dual-mode operation. It covers wide-variety of applications requiring nanometer-level precision. |
