Here are a few. The last two fit your bill (two wavelengths one is "and" the other is "or"). Hope these or the references within help!

Article Photoengineering of Bone Repair Processes
Dear Dr
ABSTRACT
Objective: This paper aims to report the state of the art with respect to photoengineering of bone repair using
laser therapy. Background Data: Laser therapy has been reported as an important tool to positively stimulate
bone both in vivo and in vitro. These results indicate that photophysical and photochemical properties of some
wavelengths are primarily responsible for the tissue responses. The use of correct and appropriate parameters
has been shown to be effective in the promotion of a positive biomodulative effect in healing bone. Methods:
A series of papers reporting the effects of laser therapy on bone cells and tissue are presented, and new
and promising protocols developed by our group are presented. Results: The results of our studies and others
indicate that bone irradiated mostly with infrared (IR) wavelengths shows increased osteoblastic proliferation,
collagen deposition, and bone neorformation when compared to nonirradiated bone. Further, the effect
of laser therapy is more effective if the treatment is carried out at early stages when high cellular proliferation
occurs. Vascular responses to laser therapy were also suggested as one of the possible mechanisms responsible
for the positive clinical results observed following laser therapy. It still remains uncertain if bone stimulation
by laser light is a general effect or if the isolate stimulation of osteoblasts is possible. Conclusion: It is possible
that the laser therapy effect on bone regeneration depends not only on the total dose of irradiation, but also on
the irradiation time and the irradiation mode. The threshold parameter energy density and intensity are biologically
independent of one another. This independence accounts for the success and the failure of laser therapy
achieved at low-energy density levels.
