Below in conjunction with specific embodiment and accompanying drawing the present invention is further specified, but its qualification of not opposing.
In Fig. 2, provided blue laser of the present invention structural representation in one embodiment.As shown in Figure 2, this blue laser comprises: LD pump light source 101, laser crystal 102 and frequency-doubling crystal 103.Explain respectively in the face of structure, function and the realization of the above-mentioned parts in this blue laser down.
Wherein, LD pump light source 101 is used to launch pump light; Said pumping light wavelength can have multiple possibility, and for example, wavelength is the pump light of 808nm, or wavelength is the pump light of 880nm.In the present embodiment, the pumping light wavelength of said LD pump light source 101 emissions is 808nm.
Laser crystal 102 is used for converting the pump light of LD pump light source 101 emissions into fundamental frequency light.Fig. 3 is the sketch map of two films that end face plated of laser crystal described in the present embodiment; As shown in Figure 3; On the incidence surface of laser crystal 102, be coated with the pump light high transmittance film; Fundamental frequency light high-reflecting film and frequency doubled light high-reflecting film then are coated with pump light partial reflection film on the exiting surface of laser crystal 102, fundamental frequency light high transmittance film and frequency doubled light high transmittance film.
As what mentioned in the background technology; Laser crystal in blue laser can't improve the absorptivity of said laser crystal to pump light through improving doping content; Therefore; Compare with prior art shown in Figure 1, in the present embodiment, on the exiting surface of said laser crystal 102, also be coated with pump light partial reflection film; This makes the pump light that is not absorbed by laser crystal 102 can be reflected back toward said laser crystal 102 inside when arriving on the exiting surface that is coated with said pump light partial reflection film; Laser crystal 102 is absorptive pumping light once more, improves the absorptivity to pump light, makes laser crystal 102 can under lower doping content, improve the pump light absorptivity.In addition; Light path according to blue laser; The unabsorbed pump light of laser crystal can be incided in the frequency-doubling crystal 103; Cause the thermal effect of frequency-doubling crystal, therefore, also help improving the stability of said frequency-doubling crystal 103 through coating pump light partial reflection film on the exiting surface of laser crystal 102.
The selection of said pump light partial reflection film is relevant with the concrete wavelength of said pump light.In the present embodiment; The pumping light wavelength that said LD pump light source 101 is sent is 808nm; Said laser crystal 102 is that the pump light of 808nm converts the fundamental frequency light that wavelength is 912nm to said wavelength, and said frequency-doubling crystal 103 is that the fundamental frequency light of 912nm converts the frequency doubled light that wavelength is 456nm into said wavelength.Therefore the pump light partial reflection film on the exiting surface of laser crystal 102 is the partial reflection film of the light of 808nm for being fit to reflection wavelength.In addition; In the present embodiment; Pump light high transmittance film on the incidence surface of said laser crystal 102 is the high transmittance film of the light of 808nm for being fit to see through wavelength; Said fundamental frequency light high-reflecting film is the high-reflecting film of the light of 912nm for being fit to reflection wavelength, and said fundamental frequency light high transmittance film is the high transmittance film of the light of 912nm for being fit to see through wavelength.
Need to prove; Going out the inner pump light of reflected back laser crystal from the pump light partial reflection film of laser crystal can not all be absorbed by laser crystal again; Also can be transmitted to LD pump light source 101 by some incidence surface, and LD pump light source 101 there is damage threshold, when the light that sends when LD pump light source 101 is reflected to self once more from laser crystal; If catoptrical luminous power is greater than this damage threshold; Will damage LD pump light source 101, therefore, when confirming the reflectivity of pump light partial reflection film; Can confirm according to following principle: should guarantee that said pump light reflectance coating can improve the absorptivity of laser crystal to pump light, the luminous power after the pump light of guaranteeing reflected back again transmits from the incidence surface of laser crystal 102 is less than the damage threshold of LD pump light source 101.
