Photo-acoustic Cell
                                                -- an enconomic way to calibrate narrow bandwidth IR lasers

OPOs have extended the laser radiation from visible to the Infra-Red, and have opened a new area for spectroscopists, and the demand to accurately calibrate laser wavelength/bandwidth in the IR is high.

Based on photo-acoustic signal, photo-acoustic cells provide a simple and reliable way to calibrate laser wavelength/bandwidth in the IR. U-Oplaz is pleased to introduce our Photo-acoustic Cell.

This photo-acoustic cell comes with a gas volume of 12ml, equipped with stainless valve for the control of gas flow and standard 1/4” Tube connectors. The two windows are made of UV grade fused silica and Sapphire respectively. This allow the users to calibrate wavelengths from 200 nm to 5 mm, without having to change the optics. A micro-speakerphone which is most sensitive to sound at the photo-acoustic frequency is used to give maximum signal to noise ratio. The cell body is composed of a nickel-coated aluminum, allow you to use a variety of gases with this cell. Measurements can be performed from 2 atmospheric pressures to a few milli-torr. Pre-amplified signal output is in a standard BNC connector, could be directly connect to the Oscilloscope.

Diode laser seeded OPO BBO-2S, KTP-2S
                                                                                                   -- transform limited resolution, reliable and efficient

Based on the patented ring cavity used in BBO-3D, our diode laser seeded OPO allows one to seed the ring cavity without active control of the cavity length, thus significantly improving the stability of the system. In our standard model, we offer you a complete system which includes the tunable diode laser and the OPO cavity. With available diodes in the market right now, this OPO covers 650nm to 2200nm when pumped by the second harmonics from a seeded Nd:YAG source.

Specifications:

Specification	Value	Comments
Nd:YAG pump requirement¹	<30 MW/cm²lasing threshold	single frequency, smooth profile (gaussian or flat top)
Output pulse energy	see power spectrum	efficiency depend on total pump energy
Bandwidth	down to 0.01 cm^-1	close to transform limited resolution
Seed laser requirepment	>1mW CW source	single mode diode laser or CW dye laser
Long term stability	same as seed source	the most stable OPOs in the market
