Optical-parametric oscillator
1064 nm, 10 W
Qioptiq
for laser spectroscopy
Qioptiq's standard device, the OS 4500, is a compact, all-in-one
continuous-wave laser source combining excellent spectral properties
with an extremely large tuning range.
Among its special features:
- Single Frequency Operation
- Narrow Linewidth
- Low Noise
- Outstanding Beam Quality
Such features make it the ideal tool for high-resolution spectroscopy and
many other applications requiring precision metrology in the infrared
spectral region.
The OS 4500 system is an optical parametric oscillator (OPO) completely
equipped with control and stabilization electronics as well as an
integrated pump laser. Its output is converted into signal and idler
radiation in a nonlinear crystal (periodically poled, MgO doped lithium
niobate). The crystal is placed inside an optical resonator which forms
the actual OPO. An intra-cavity etalon (ICE) ensures stable single-
frequency operation.
The large emission range for signal (1.38 - 2.00 µm) and idler (2.28 -
4.67 µm) radiation is achieved by integrating several poling periods on a
single crystal. The system can be tuned to the desired emission frequency
without changing optical components. Output powers on the order of 10s
of mW are achieved.
