Pricing and Lead time for Ultra-50 794.7nm Brightlock lasers

As per our conversation at JLab on Friday, Oclaro (Newport Spectra Physics) no longer manufactures the line-narrowed lasers we bought in the past couple/few years. A new company offers a slightly less narrowed replacement: QPC Lasers. Sales Engineer Merrill Apter is a colleague of Rick Frost, formerly from Spectra-Physics.

Hi Al,

By way of this email I'd like to formally re-introduce myself to you. I'm now Vice President of Business Development at QPC Lasers (www.qpclasers.com<http://www.qpclasers.com/>). The reason for my email is that I've been informed that Oclaro is obsoleting their VBGed 794.7nm Comet laser and to ensure that the many customers who have previously purchased this product have an alternative supply we are coordinating activities with their sales and marketing force in a seamless transition moving the Oclaro customers to us. As you probably know we have a mature, commercial product with enhanced performance when compared to what Oclaro offered.

We commercially offer a 25W Brightlock product where the light is delivered via a 400um diameter, 0.22NA fiber jumper. If you can tolerate a larger aperture (600um diameter, 0.22NA fiber jumper) we can rate the Ultra-50 Brightlock module to 30-watts, CW.

As a proof statement to the performance of our Brightlock product, I've included a final test data sheet from a recently manufactured Ultra-50 Brightlock module. You should also know that both our 25-watt and 30-watt product can be supported by our newly introduced turnkey solution named S-Ultra (commercial data sheet attached).

To ensure that our customers are spending their valuable time with their experiments and less time trying to cool, drive and control these diodes we recently (Photonics West, January 2011)introduced our (System Ultra) S-Ultra turnkey solution. The unit price for either a 25-watt or 30-watt S-Ultra is $15,900. Delivery is 8-10 weeks ARO. The unit price for the Ultra-50 Brightlock @ 794.5nm is as follows: $5000.00 (25-watt version), $5150.00 (30-watt version).

We also have fiber-coupled modules rated up to 150W, CW (see datasheets for Ultra-100 and Ultra-500) which can be sold with stand alone diode drivers and thermal platforms.

As you probably recall the benefits of our Brightlock technology is 4 fold, Brightlock technology is an on-chip Bragg grating which offers these 4 key benefits: 1) Locks the wavelength centroid +/-1nm over a 30 degree C ambient change 2) Has minimal impact to the overall E2O efficiency 3) Spectral width narrowing @ FWHM typically to < 0.5nm 4) The diode laser is highly insensitive to temperature changes, although as opposed to VBGs there is fine tuning capability. As you know a non-VBGed/conventional diode has a wavelength shift as a function of temperature of 0.3nm/C, a VBGed diode laser has no tuning capability while the Brightlock technology has a wavelength shift coefficient of 0.07nm/C.

Finally I've included a publication that will provide more details about our Brightlock technology and how it compares to VBG technology.

If you need more information or pricing about our modules or S-Ultra turnkey solution do not hesitate to contact me.
