Laser diode (LD) with stabilized frequency of output light has been developed until now. In this time, we adopted a single-mode, single-wavelength LD with a stabilized frequency for a pumping LD to end-pump microchip Nd:YVO4 lasers. In these experiment, we succeeded in obtaining higher optical-optical conversion efficiency and slope efficiency than when using conventional LD. Output laser power is insensitive to temperature of LD, and output could be kept stable and almost constant until temperature of LD was as high as 35 ℃. In the future, a low-cost end-pump microchip laser that does not require a temperature control mechanism should be developed.
