NICHIA DIODES

Dave,
If you still have a GGW-H20l sled laying around that you would be willing to trade I'll happily buy a 405 from O-Like ( http://www.o-like.com/b2b_cpinfo.asp?id=914 ) and have it delivered to you for a thorough "OK... just relax... you are going to feel some pressure..." examination.  
How 'bout it?   :

That would be tempting **IF** I had a GGW here.  I just placed my last one into a warranty repair.

LOL ;D  Sorry to waist your time.  It's new to me though!! ;D[/quote]


Research is rarely a "waste of time."  We just need to use these early numbers to figure out what is happening today.

Peace,
dave

I got a quote from a fella in Japan. He said he was the contact for Nichia here is the e- mail.


Thank you for your interest in our Laser Diode. My name is Hiromasa Omiya and I am responsible for LD customers in US, Canada, South America. I will be your contact person. Please contact me for orders and any questions as for laser diodes. If you need an official quotation, please let me know your required quantity with the following parts number.

1. PRICE
Currently unit prices for the minimum shipping quantity (1 piece) are as follows:

- Violet 405 nm
NDV4313 (Transverse single-mode 120mW): JPY 210,000/each
NDHV220APA (Transverse multi-mode 200mW, engineering sample) :JPY260,000/each


Above prices include Freight by courier, not include any taxes. Standard lead time 2 weeks. In accordance with bigger shipping quantities, appropriate discounts shall be applied.

That comes to $2,600.00 USD.

I just talked to Susie and they are now selling those Nichia diodes one at a time. Similar to a 6X.

Very true! Could we do a group buy?

We probably want someone to test how long these can be run and at what wattage before that

Still - these look MUCH more promising than the AW210s

Any takers?

Edit: it would help if I quoted the post I was replying to...

Edit 2: oops - I saw the graph, but missed the thread that established about 170-180 mA as a fairly safe limit for driving these diodes - apparently they are more efficient than the GGW-H20L diodes, but can't be driven as high.
