November 10, 2006 – Pavilion Integration Corp. (PIC), a manufacturer of high
performance laser sources, announced that it is expanding its WhisperIT™
product line by adding fiber-coupled versions of its miniature red laser modules.
These are housed in the same compact package as the free-space versions,
with a hardwired fiber pigtail output format. These highly reliable, field-proven
modules meet or exceed stringent customer requirements for low noise, excellent
beam quality and highly stable output power, as well as long life. Additionally, they
have very fast warm-up time, dissipate very little heat, and are highly cost-effective.
The fiber-coupled versions are available with either regular Single-mode fiber, PM
singlemode fiber or Multi-mode fiber. An FC/PC connector is the standard fiber
termination, however other common connector types can be provided instead. Also
available is the FRH (Fiber Remote Head) option that adds APC (Automatic Power
Control) at the fiber output end face, to provide the highest possible output power
stability.
The PIC fiber-coupled WhisperIT™ red lasers are highly suited for instrumentation,
metrology, inspection, and reprographics applications. In particular, these devices
are ideally suited for semiconductor wafer metrology, since they have very low
intensity noise (RIN better than 130 dB down) over a broad frequency range and an
excellent beam profile that is stable long-term. These applications are further
enabled by the excellent polarization contrast of the PM fiber output. Like others in
the WhisperIT™ family, these are fully integrated, full-time low-noise, CW
solid-state lasers, and are all packaged in an identical housing design. A broad
range of single and multi wavelength versions with freespace or fiber-coupled
output formats are available across the spectrum (from near-UV across the visible
into the near-IR).
