Optical Parametric Oscillators  
                                                                                -- covering 410nm to 2500nm start at $9,000

BBO-3B I
                      -- low cost, high efficiency, price starts at $9,000(US Price), $13,000 fully automatic computer control

BBO-3B I OPO is the most affordable and the most efficienct OPO in the market -- up to 65% efficiency. Its simple design also lends to its reliability.

¹ BBO-3B has been tested and proven to work well with most existing ns pulsed Nd:YAG lasers that have a Gaussion output coupling mirror. These systems include all the GCR models from Spectra-Physics, PowerLite series from Continuum and many others, even non TEM₀₀ mode pump sources.

2 Lasing threshold depends on the model of the BBO-3B I. We offer three models for BBO-3B I. Model HE is the High Efficiency model whose lasing threhsold is below 20 MW/cm². Model S is the Standard model whose lasing threhsold is below 30 MW/cm²,r –¾’©11, and has a smaller beam divergence. Model R is the Ring cavity model, whose lasing threshold is also below 30 MW/cm², and has the highest damage threshold.

3 Beam diameter depends on input pump beam size. The value given in the table are measured right after the output coupler of the OPO cavity.

Power spectrum of BBO-3B I model HE, pump beam diameter 5.5 mm, total pump energy 135 mJ. (Pump laser is a GCR-16 Nd:YAG laser from Spectra-Physics, 355 nm pump pulse length 7-8 ns).

Bandwidth spectrum of BBO-3B I model HE with the same pump specification as the chart above. The pump laser is also operating on a single longitudinal mode. Nd:YAG pump lasers without a seeder will see a 50% to 100% increase in bandwidth across the tuning range.

Other Broadband OPOs, OPO Doublers & Accessories

With other high quality NLO crystals, we also offer the BBO-2B and KTP-2B which are pumped at 532 nm. They could extend the spectrum out to 4 mm. Our OPO Doublers will cover the spectrum from 210 nm to 420 nm, and with our special designs it could reach a doubling efficiency of 45% -- the highest efficiency in the market.

Upgradability

BBO-3B I could be upgraded conveniently in two ways -- model HE and model S could be upgraded to BBO-3B II; model R could be upgraded to Dye Laser Seeded or Diode Laser Seeded OPOs.

BBO-3B II
                                  -- a simple way to a consistently narrow bandwidth 

By using a type II BBO crystal instead of a type I BBO crystal, the BBO-3B II gives a consistently narrow bandwidth over the same tuning range as the BBO-3B I while maintaining the simple design of the BBO-3B I and high efficiency. The efficiency for doubling the narrow band-width output of this OPO is as high as 45%.

¹ Bandwidth depends on pump intensity, beam size, divergence and pump bandwidth. For single frequency pump sources the maximum bandwidth ranges from sub-cm^-1 to below 2 cm^-1, e.g. from 1500nm to 2200nm BBO-3B II gives <1 cm^-1 resolution.

Physical Layout:

Same as BBO-3B I, could be upgraded from BBO-3B I by changing the modularized tuning block.
