This TO-56 Green laser should fit many of the hosts we are currently using:
Here is a little more info on the very-efficient PPLN (periodically poled lithium niobate) conversion:
Should be good for 120mw or so.

Finnish start-up EpiCrystals Inc. has announced what it claims is “the smallest and most efficient green light source for pico projectors.” EpiCrystal’s game plan is that RGB (red, green, blue) laser technology will revolutionize smartphones, enabling them to project photos, video presentations and movies on almost any surface with HD-level quality and resolution. The green laser module will be available in Q1, 2012 for $45.00 in 10K volumes.
EpiCrystal Vice President of Business Development Tomi Jouhti sent these details:
• Laser has two main components: GaAs-based 1064nm IR laser chip and a PPLN waveguide type nonlinear crystal
• Laser chip has an integrated 45-degree folding mirror and lens (both are made at wafer level) for efficient coupling
• Bright true green color (532nm)
• Laser operates in passively Q-switched mode (very simple construction, three-contact laser)
• Wide band QPM (quasi phase matching) in the crystal
• Wide band SBG (surface Bragg grating) in the crystal
• SBG locks the central frequency of the IR laser
• Spectrum width 0.5-1.0nm –> reduced speckle
• 60+ mW optical output power
• 100+ MHz modulation speed
• TO56 module, volume ~0.2cc
