This Section describes commonly available solid state laser diodes. 

== 405nm ==
These diodes are a deep violet (near-UV). Commonly used in Blu-ray devices (including game consoles and Blu-ray recorders), these diodes range in power from 100mW up to 500mW. These diodes have a very high Vdrop (approaching 6V) at higher current levels; consequently, a driver that can deliver this additional forward voltage must be used. 

Most commonly these diodes are made available in the original drive sled; the diode must be extracted from the sled before use.

Diodes are classified either by the sled from which they came (in the case of readers) or by write speed (in the case of writers). Listed below are some of the most commonly-found 405nm diodes. (Brackets indicated data to be added soon as I find it)


* PHR-803T - ~100mW (Other vital stats here) (XBox HD-DVD Add-on Module)
* SF-AW210 - ~200mW (Other vital stats here) (4x - 6x Blu-Ray Writer)
* BDR-205 (12x) - ~500+mW (Other vital stats here) (From Pioneer BDR-205 12x Blu-Ray Writer)
* BDR-S06J (12x) - ~500mW (Other vital stats here) (OEM Pioneer 12x sled for Blu-Ray Writers) 
* SF-BW512L (12x) - ~500mW (Other vital stats here) (Common OEM sled found, amongst other places, in LiteOn Blu-Ray Writers)


All diodes listed are single-mode, single-emitter. It is recommended to use AR-coated glass optics at output powers upwards of 200mW to prevent the lens/lens housing from melting and possibly damaging the diode.

== 445nm ==
These diodes emit a deep indigo blue (individual perception is subjective, but the common description seems to be that of a deep blue spot/beam with a purplish aura). These diodes are commonly extracted from high-efficiency data projectors.

Diodes are named after the projector model/series they are extracted from. 


*A-130 
-One watt 445 with a 4.7v forward voltage. 1mw/ma curve.  Diode is case isolated.  Diode pin out: 
 
                            o  <--diode case (not used)
  positive, (+) anode-->  o   o  <--negative, (-) cathode
            
*A-140
A higher-binned version of the A-130. Output is often on par with the A-130 (the A-140 is described as having a higher efficiency than the A-130 series). These diodes are capable of outputting in excess of 2W; however, for lifetime purposes it is recommended not to exceed a current of 1.6-1.7A (for 1.5W out after optics). Threshold of approximately 250mA

*1600
The 'new kid on the block'. Test data coming soon.

Diode is case isolated with two pins.  Diode pin out:
 
                            v  <--diode case notch
  positive, (+) anode-->  o   o  <--negative, (-) cathode
                
It is recommended to use  AR-coated glass optics at output powers upwards of 200mW to prevent the  lens/lens housing from melting and possibly damaging the diode.

All 445nm high-powered diodes are multi-mode, single-emitter. These diodes will require fast axis correction optics to achieve equal divergence on both beam axes.

Not really a direct diode (maybe this should not be here)?
This is a custom module built by Osram for the micro projector market.

== 532nm ==
 This is a [[DPSS Green]]

This is a single-mode diode. It has a nice small beam with a good  deep(ish) red color. The down side is they are expensive and don't make  much over 150mw. If they could get powers higher these would be the  diode to have.  It has a small emitter, and makes a nice small beam.

LPC826P diode 200mW 660nm 400mA

== 808nm ==
Infrared-wavelength Diodes, commonly used as a pump-source for exciting Nd:YAG ''(neodymium-doped yttrium aluminium garnet)'' or Nd:YVO4 ''(neodymium-doped yttrium orthovanadate)'' crystals, for SHG- ''(second-harmonic generation)'' doubling to produce green laser-light at 532nm. ''(See Wikipedia article on 'DPSS' (Diode Pumped Solid-State) Lasers- [http://en.wikipedia.org/wiki/Diode-pumped_solid-state_laser External Wikipedia Article on 'DPSS' Lasers])'' Other crystals ''(ie: BBO, LBO)'' are also pumped by 808 to produce other wavelengths, such as Blue, Violet, and even Yellow.
